Tawhidi Islamic economics in reference to the methodology arising from the Qur ʾ an and the Sunnah

Purpose – The purpose of this paper is to lay down the methodological structure of the epistemology of tawhid (Oneness of Allah). In this paper, the meaning of tawhid also refers to the monotheistic unity of knowledge (consilience) in the cast of its organic pairing by circular causation relations between themoral and material possibilities. The paper thereby raises the critique of mainstream economic reasoning and its imitation by existing Islamic economics. Consequently, by the ontological, epistemological and phenomenological foundation of tawhidi methodological worldview, an altogether new socio-scientific reasoning in generality and economic reasoning in particular is introduced. Design/methodology/approach – The socio-scientific methodological reasoning of unity of knowledge according to the tawhidi methodological worldview is introduced contrary to the inept rational choice postulates of mainstream economic reasoning and its imitation by existing notions of Islamic economics. The method of instructing students in the light of this approach according to Tawhidi Islamic Economics (TIE) is introduced from the existing literature. Findings – The existing nature of mainstream economics and its imitation by Islamic economics is critically deconstructed and replaced by the true epistemological, ontological and phenomenological perspectives of TIE in the world of learning. Some inner properties of such a methodological study of TIE are laid bare for further investigation. Originality/value – This is the first paper of its kind in this journal to expound the original and most creative methodological worldview that Islamic economics must bear. This is the foundation of the development of the true stance of Islamic economics and finance.

contemporary approach to the study of Islamic economics to be thirty years.The works of great Islamic scholars, mujtahids such as Imam Ghaz alī, Ibn Taymiyyah, Imam Sh a Á tibī, Ibn Qayyim and Ibn Khaldūn, recorded the study of Islamic economic and social problems either in reference to the Qurʾ an and Sunnah (prophetic teachings) or independently of these as intellection borrowed from Greek social and economic thought.Examples of the latter include Ibn Khaldūn (Rosenthal, 1958) and the Muslim philosopher of Greek vintage, Al-Farabi (Waltzer, 1985).The use of the term "Islamic economics" is an imitation of contemporary intellectual fashion.It reflects the classification of educational disciplines left to us by the Occidental world.Such classification is devoid of the integrated beginnings of intellectual thought in which all Muslim scholars once immersed themselves in the search for knowledge.That search was not confined to this or that discipline but was, rather, conducted with an understanding that placed all disciplines within a comprehensive methodological worldview.This paper will address the socio-scientific methodology of holism emerging from the true foundation of Islamthat is, tawhid as the monotheistic law of everything.Islamic economics, finance, science and society are studied within transdisciplinary holism under the primal ontology of tawhid and its methodological worldview.
As the classification of disciplines carried with it specialization and the independence of each area of learning, the spirit of holism disappeared.Islamic economics, under its contemporary rubric, has embodied such separable thinking at the loss of an integrative methodology that once made it relevant to everything.The proposed corrective methodological worldview is premised on "everything" and must therefore properly define its permanent epistemological basis.
Such a grounding of the Islamic economic discipline has remained absent since its terminological inception.Over the years, a methodical dissociation of Islamic moral and ethical issues that are inherent as endogenous inter-causality failed to assume the methodological worldview in global learning.
As the spirit of Western erudition entered lock, stock and barrel into Muslim thought, the original hallmarks of Islamic science and society were superseded.This process affected economics, which never developed a foundation, form or critical learning process to be pursued via Islamic epistemology, meaning the theory of knowledge expressed in a significantly analytical form.This marked the departure of the Islamic methodological worldview and its potential to contribute uniquely Islamic erudition, epistemology and consequential analytics to the world of learning (Choudhury, 2017).
Thus, Islamic economics entered the scene of the classified disciplines in a subservient state to existing mainstream economic and socio-scientific thought, devoid of its epistemological worldview informing an analytical perspective.Consequently, almost all of its argumentation, modeling, formalism, applications and inferences took the path of Western interpretations.The work of Mahomedy (2013) can be referred to for an incisive and insightful critique of the existing field of Islamic economics.Nonetheless, high potential remains for Islamic economics as a discipline of meta-science that is grounded on the truly Islamic epistemological foundations.These are, namely, the exegesis of the Qurʾ an and Sunnah in respect of the tawhidi (monotheistic, consilience and unity of knowledge) methodological worldview.
Present-day Islamic economics is in a dire state.It is not original; it is failing to be derived from the teachings of the Qurʾ an, Sunnah or Islamic scholastic thought.This is not to say that the Qurʾ an is the divine book of science.Rather it is the revealed book of guidance for those who seek guidance (Qurʾ an, 2:2).Nonetheless, it is the revealed book that is complete and final in knowledge.It thus provides guidance for all issues of mind and matter, and thus of science, economics and worldly matters in its meta-perspective of morality and ethics.

Islamic economics in its present state does not have a theory and foundation that can be called truly "Islamic" in terms of systematizing economic and social learning in a holistic way.Such an approach would emphasize inter-causality on the precept of unity of knowledge.The methods and models of Islamic economics today ignore the need to model Islamic morals and ethics in an endogenous way with materiality.The implications are thereby a borrowing and an interpretation that is either crassly Islamic, yet without the spirit, rigor and foundations or is parroting the Western methodological worldview.Only an outer semblance of Islamic values is attached to the economic reasoning of the present-day notion of Islamic economics [1].

Research objective
This paper focuses on the importance of the epistemological derivation of scientific methodology as the inevitable commencement of scientific thinking.There cannot be any scientific methodology without the foundation of the epistemological, ontological and phenomenological details of the underlying worldview and its specific application to selected issues of scientific inquiry.
The objective of this paper is to establish the indispensable fact that the socio-scientific epistemology of the Islamic worldview is premised on the analytical understanding of tawhid in relation to the generality and particulars of the world-system.This foundational methodological worldview emerges from the Qurʾ an.It is transmitted by the Sunnah and thereby takes the path of learned discourse.In socio-scientific jargon, the tawhidi methodological worldview takes up the ontology, epistemology and phenomenology of the precept of unity of knowledge (consilience).This paper will establish this fact regarding the approach to studying Islamic economics as a particular case of the vaster methodological worldview of tawhid.The paper argues that such a foundational methodological worldview of Islamic socio-scientific thought has been fully missed in anything called Islamic economics and finance.In fact, it is missing in the whole socio-scientific domain.It is direly needed if Islamic economics and finance in particular and Islamic socio-scientific thought in general are to contribute to global scholarship and practical application for the well-being of all.
This paper is classified in the following critical viewpoints: the first part is an introduction to the current problems of economic reasoning in orthodox economics, which today's Islamic economics has imitated.A critique is launched of mainstream and Islamic economics from the perspective of a methodological worldview.The second part is an introduction of the epistemological, ontological and phenomenological premises of true Islamic economic thought based on the tawhidi methodological worldview.The third part brings out the methodological organization of the proposed reconstruction of Islamic economics on the basis of its essential methodology of tawhid.Hence, we term the emergent economic science as Tawhidi Islamic Economics (TIE).The fourth part, as conclusion, continues with a suggested approach to the study of TIE.
The present state of the study of economics and Islamic economics: a brief reference to the literature The Royal Economic Society points out that smaller universities in the UK have abandoned exclusive focus on economics since the year 1999.However, the larger universities in the UK, by virtue of their advanced ideas in economic reasoning and by integrating related disciplines, have flourished.The large universities are those that are reputably established.One such area that has arisen in the larger universities is heterodox economic theory.
Subsequent to the heyday of Islamic economics in the Muslim world, it has by and large been supplanted by the now stylized caption of Islamic finance.This is an equally problematic field in its imitation of mainstream finance, having only a palliative of Islamic instrumentation.This garb of Islamic finance is not epistemologically different or revolutionary in nature.Much has been lost from the beginning to the present (Wilson, 2014;Siddiqi, 2014).
The problem of Islamic learning started when it got increasingly dissociated from its epistemological origin in the Qurʾ an, Sunnah and intellectual discourse around these sources.That discourse is called "ijtih ad", meaning authentic research based on epistemological foundations.This being the case, the axioms, assumptions, nature, methodology and applications of the core of Islamic economic reasoning, namely morality and ethics, have been marginalized.They have been replaced by substitutes imported from a commercial and materialist outlook.An example is the present failing of Islamic banks.They raise large equity values from the shares market.However, they remain oblivious of the cognition and practice of the Islamic methodological worldview applied to the commercial arena in the form of endogenously induced well-being (ma Á sla Á hah) (Furqani and Haneef, 2012).According to orthodox economic theoryto which neoclassical economics belongsthe principal attribute of rational choice regarding goods and services is "marginal rate of substitution" between competing goods and services for command over scarce resource allocation between such competing ends.We will refer to this neoclassical premise as "marginalism".Likewise, Islamic economics immersed in mainstream orthodox economics could not emerge as a project within the sociological economic school that pronounces the principle of pervasive complementarities.This is the principle that arises from the understanding of organic inter-causality of learning in unity of knowledge between variables and their functions.This predicament is caused by it being immersed in the traditional microeconomic and macroeconomics branches of mainstream reasoning.There was blind acceptance to the underlying postulates of orthodox and mainstream economics with their traditional orientation.This is despite the fact that such orientations are being seriously questioned in mainstream economics by the works in rational expectation theory.The fields of microeconomic foundations of macroeconomics were the results of such theorizing.In Islamic economics of today, such original ideas of formalizing the ethical place of microeconomics in the development of the macroeconomic consequences did not arise.Islamic economics thus blindly followed the traditional theories of microeconomic and macroeconomics.Yet, in none of these followings is there any robust theory of endogenous ethical integration in economic theory, formalism and application (Mahomedy, 2017).
The major problem of Islamic economics like Islamic finance, Islamic banking and other Islamic socio-scientific ventures is that it has no articulated epistemological foundation.On the other hand, any science, whether social or natural, must be based on a solid epistemological foundation.Such an orientation subsequently provides axioms, assumptions and methodological formalism to the entire body of theory and application.Einstein said that science without epistemology remains muddle-headed (Bohr, 1988).
The rise of heterodox economics in recent times is of a deeply ontological and epistemological origin.Even neoclassical economics is epistemological in nature according to its own axiom of economic rationality.Classical economics is thoroughly epistemological in reference to the Theory of Moral Sentiments as Adam Smith's first great epistemological contribution to economic reasoning with endowed morality.All of the science that we have inherited rests on the epistemology of heteronomy (Bhaskar, 1978).Heteronomy conveys the nature of dualism between a priori and a posteriori domains of reasoning.Such issues can be discussed to bring out the distinctive difference between rationalism of the Occidental theory of science and the episteme of unity of knowledge of the tawhidi methodological worldview.
Tawhid as the foundational Islamic methodological worldview: the advent of Tawhidi Islamic economics Contrary to all such epistemological moorings, today's Islamic economics, as well as all other Islamic socio-scientific fields in recent times, have not been able to formalize and contribute to the internal dynamics and functioning of the primal axiom of the entire Islamic methodological worldview upon which a meta-science can be erected.This is the ineluctable axiom of tawhid as the monotheistic law of unity of knowledge.It exists not simply in utterance.Rather, as Imam Ghazali said, the understanding of tawhid as methodological worldview has sixty stages with increasing depth (Karim, 2018).Islamic economics casually adopted an utterance around the outer husk of declaring tawhidi belief without knowing its world-system dynamics and axiomatic character in the building of socio-scientific thought, meta-science and applications (Naqvi, 2003).
The tawhidi methodological worldview is the universal and unique foundation of all Islamic intellection.It is formal in nature if properly used for the construction of the cognitive and material world-system and its specifics.Such formal intellection with its methodology, methods and application is equally applicable to the building of meta-science in the entire world of learning.On the indispensability of the tawhidi methodological worldview in the mundane world-system, Ibn Arabi wrote in his Futuhat (Ibn al-Arabi trans.Chittick, 1989): The first way is by way of unveiling.It is an incontrovertible knowledge which is actualized through unveiling and which man finds in him.He receives no obfuscation along with it and is not able to repel it[. ..].The second way is the way of reflection and reasoning (istidlal) through rational demonstration (burhan `aqli).This way is lower than the first way, since he who bases his consideration upon proof can be visited by obfuscations which detract from his proof, and only with difficulty can he remove them.
The Islamic economic approach, which only utters tawhid at the beginning and at the roots, is unable to formalize the monotheistic meaning as a methodology, formalism and application.Contrary to this narrow attitude is the induction of the progressive knowledge of unraveling the tawhidi methodological worldview into socio-science and economics.We will thereby refer to the tawhidi epistemological foundation of Islamic economic science by the term TIE.
In TIE, consequently, the Kantian problematique of heteronomy as enforced partition between the moral imperative of the a priori domain and the practical reasoning of the a posteriori domain has entered Islamic socio-scientific thought in general and Islamic economics and finance in particular in a most surreptitious way.Heteronomy is of the nature of rationalism in causing enforced dichotomy between the moral law (tawhid = a priori) and the world-system (a posteriori).
Contrarily, the Qurʾ an presents the moral and cognitive world-systems as being unified and indivisible holism.It bears its endogenous dynamics of organic unity of being and becoming concerning mind and matter.The tawhidi methodological worldview is thus indispensably required to give the universally and uniquely original, revolutionary, essential Islamic foundation to what may be referred to as TIE and finance, science and society (Choudhury, 2014).
As was mentioned above, Islamic socio-scientific intellection in general and Islamic economics and finance in particular have not been able to blaze the emergence of a field of heterodox economics.Heterodox economics by itself is a deeply ontological and epistemological inquiry (Lawson, 2003).If the ontological and epistemological foundations of the Qurʾ an and Sunnah are missed out, then the constructive dynamics of the tawhidi foundation of organic unity of knowledge cannot be understood.This is equivalent to uttering but not knowing how to cognize and apply the methodology of tawhid in the building of meta-science for rendering to the world of learning.
Will it stay this way?Have not the Qurʾ an and Sunnah given the challenge to raise the world-system to the pinnacle of knowledge for global learning and well-being?The possibility is not to be found in the present state of Islamic thought by missing out the episteme of tawhid.Yet, substantive effort and contributions in this direction persist.
The nature of Islamic economics according to the tawhidi episteme The present paper elaborates on the epistemological methodology of tawhid for the groundwork of a heterodox Islamic economics and finance.The resultant tawhidi methodology is found to be rigorously analytical, invoking science, formalism and analytical depth, as well as universal application to particular issues and problems.It is a gross mistake and complete denial of scholarly knowledge to say that tawhid is sheerly philosophical and that deep erudition of it in Islamic economics is not understood.On the other hand, Choudhury's scholarly works in the area of tawhidi methodology have been well published in the West, addressing problems and issues directly of Islamic economics and other ones globally.
The fundamental attributes of Islamic economics in the light of tawhidi methodology (TIE) is to start from the exegesis of the principle of "pairing" in the Qurʾ an [2].Pairing conveys the meaning of organic unity between the good things of life and contrarily also conveying association of the bad things of life in accordance to the Qurʾ an.The good things are to be accepted, the bad things shunned.Pairing as organic unity of knowledge conveys the universal meaning of God's creation and purpose.It is a reflection of the unity of being and becoming along the dynamics of forming complementarities between the good and recommended things of life.The good things of life participate and complement in unity of inter-causal relationship.The bad things compete and marginalize each other.There is no scope of unifying for purposive unity, except to marginalize each other by association and differentiation.In Islamic economics, borrowing from mainstream and orthodox economics, the postulates of competition and marginalism are accepted.
This paper explains how the nature of tawhidi methodology is intellectually heightened by feedback of cause and effect circularity centered in knowledge par excellence.According to the Qurʾ an, tawhid is the bedrock of complete and absolute knowledge.God is the fullness of knowledge that is embodied in the monotheistic law as the primal ontology, meaning theory of being and existence.The world-system (ʿ alamīn) is described and is spanned by the signs of monotheistic unity of knowledge in the good things of life and its opposite in the bad things of life by participatory association and differentiation, respectively.These are both the Signs of God ( ay at Allah).They together explain the nature of the paired and the differentiated universe oppositely.They provide the ways of moral construction by consciousness of unity of knowledge in the details of the conscious universe.
Thus, the nature of Islamic economics is axiomatically premised in tawhidi methodology of unity of knowledge functioning as organic relations of being and becoming.The result is the continuous nature of evolutionary learning emerging from inter-causality between the participatory and complementary good things of life.Complementarity signifying participation presents the sure sign of paired unity of knowledge acting upon diversity of things.The world-system that is constructed by the tawhidi episteme is a continuously simulated universe of unity of knowledge.The process of participatory and complementary organic relations never ceases.It simply closes in the Hereafter.
According to the tawhidi episteme of unity of knowledge and the imminent methodology applied to Islamic economics, this paper will prove that almost all orthodox and mainstream economic thought in its critical components, is untenable in TIE.Continuous evolutionary learning in unity of knowledge results in annulment of steady-state equilibriums, optimization models, formal functions of maximization and almost all of the postulates of economic rationality.Only evolutionary learning models remain.The figments of optimization and steady state are eschewed.Evolutionary equilibrium is sustained in the evolutionary learning in the socio-scientific universe of TIE.

Critique of axioms and assumptions of Islamic economics borrowed from mainstream economics
The use of tawhidi methodology of unity of knowledge and its induction of the world-system causes almost all of the postulates of mainstream and orthodox economic theory to be null and avoid.They are replaced by the holistic, knowledge-induced, evolutionary learning of economic reasoning.Yet, Islamic economics, as we have inherited it, adheres to such postulates.The following are some of the rejections of mainstream economic theory by TIE: Scarcity: The core mainstream orthodox economic axiom is scarcity of resources.
This assumption is unacceptable in the Qurʾ anic worldview of abundance.This is true both in the absolute and relative meanings of resource scarcity.Scarcity does not exist in absolute terms by virtue of the principle of abundance in the Qurʾ an, except when resources are wasted by human acts.Yet, such states of scarcity are recoverable ones towards reviving abundance.That is, moral reconstruction is always the goal and possibility of the tawhidi evolutionary learning worldview that increases resources continuously.Scarcity of resources does not exist relatively because in the state of mutual learning and endogenous role of ethics and technology in resources, learning as by complementarities in the pairing universe of the Qurʾ an, continuously increases resources.Resources are thus endogenized continuously by knowledge.Besides, evolutionary learning causes fuzzy points of allocation of resources and competing goods everywhere along the mainstream form of "optimal" surfaces.The result then is non-existence of the concept of marginal rate of substitution, and relative prices of all kinds, which together characterize the neoclassical mainstream economic world-system in both microeconomics and macroeconomics.Scarcity by technical definition represents the resulting opportunity cost of marginalism.As fuzzy surfaces caused by continuous evolutionary learning cannot allow for marginal rate of substitution to exist and relative prices to be defined along smooth surfaces.Therefore, the postulate of scarcity must be annulled in TIE.
Opportunity cost and marginal rate of substitution (marginalism): Because of the continuously endogenous effect of interaction, integration, and evolutionary learning as properties of the pairing, i.e. complementing or participatory universe, there is no steady-state equilibrium point, and no optimal resource surface exists.In this way, the entire consumer indifference curve, welfare surfaces, and the production possibility curve do not take shape and form.
Objective functions of mainstream and orthodox economics: The non-existence of smoothly concave-to-the-origin indifference curves and production isoquants, and smooth convex-production-possibility curves imply that the well-behaved types of utility function and production function in substitutes do not exist.Besides, substitutes cannot exist in the continuously evolutionary learning by pairing the complementarities of goods, services and productive inputs.
Ethically speaking too, in the first-order condition of relationship between goods and productive inputs, the economic expansion path remains positively sloped.In the second-order condition of allocation of resources, it is possible that one of the goods and services receives differentially less than the other.But both gain along the positive economic expansion path.Such properties of the continuously learning universe negate the meaning of "priority" in resource allocation by marginalizing any choice by another.
Relative prices of goods, services, and productive factors: The non-existence of smooth indifference curves, production isoquants, and production possibility surfaces cannot allow for well-determined relative prices.
Market prices: In the absence of well-determined relative prices, consumer demand curves and market demand curves cannot exist in their smooth forms.This also happens due to the absence of a simple price-quantity relationship for a specific good in demand and supply.Rather, other critical factors militate against it and intervene as a direct consequence.Examples of such systemic interferences are dynamic preferences of choice and endogenously related variations on other characteristics, e.g.continuously variable relative prices, incomes and resources in the demand and supply functions (not curves).
Marginal cost pricing: Marginal cost of variable factors cannot exist because of knowledge-induced learning cost curves and production functions in a continuously evolutionary learning case of "everything" in the world-system.Besides, under the effect of increasing returns to scale, the total cost curve, average cost curve and the productivity curve of output altogether remain continuously evolutionary and downward shifting with endogenous learning.

Marginal productivities of productive factors:
The absence of substitution and its replacement by pervasive complementarities between goods, services and productive inputs cannot allow for marginal productivities of inputs, goods and services.All other characteristics of non-existing steady-state equilibrium and optimal points cannot allow for marginal productivities to exist.

Dynamic preferences as by induction of technological change:
The evolutionary learning properties of the utility curve (therefore consumer indifference curve) and production function (therefore production isoquants) are causally related with dynamic preferences, tastes and technology.Consequently, all the properties of rational choice theory are annulled in the presence of evolutionary learning and pervasive organic complementarities caused by the tawhidi axiom of organic unity of knowledge and its effect on the evolutionary learning (pairing) universe.
The same kind of result is true of technology.Unlike the exogenous nature of technology in mainstream orthodox economic theory, technology is endogenously determined by continuous evolutionary learning.Such learning phenomenon in unity of knowledge affects resources, preferences and choices by their mutual interaction and integration followed by continuous evolution.These are substantive characteristics of evolutionary learning TIE that are explained in detail throughout this paper.
Economic rationality: This is a mainstream orthodox axiom based on full information and pre-ordering of given preferences as datum, so as to establish internal consistency of the neoclassical theory in problem-solving.However, in Islamic economic theory according to the tawhidi methodological worldview, the postulate of full information is untenable.The tawhidi universe to which we are exposed by cognition and experience under evolutionary learning in unity of knowledge can never allow for discontinuity of knowledge (and thereby differentiation oppositely in the states of non-learning).Besides, dynamic preferences and endogenous technological change under the impact of evolutionary learning in unity of knowledge cannot be pre-ordered.Problem-solving is done not by any consistent assumption of rational choice; rather, the formal results and experiences of emergent economic and social models cause the need to address the problems at hand in pertinent ways.McCloskey (1985) promoted such an idea of addressing the nature of the state "as is" rather than by theoretical prediction of economic theory in its normative form.
Optimization and equilibrium consequences of the absence of economic rationality: The absence of the postulates of economic rationality in the tawhidi methodological worldview results in the complete absence of optimal states and steady-state equilibrium.While mainstream economics allow for exogenously induced changes in Pareto-optimal steady-state equilibriums, the tawhidi methodological worldview has only endogenous resource augmentation and changes of preferences and institutional organization under the impact of unity of knowledge.The result then is a continuously endogenous change in resource allocations, technological change, preferences and every other participatory variable.Consequently, all points on the economic surfaces are continuously perturbed by continuous change along nonoptimal directions.Likewise, steady-state equilibrium points are changes into evolutionary learning points without convergence into attained states: Economic systems: The concepts of perfectly competitive markets (economy), imperfect competition and monopolistic competition are shown to be untenable, in the continuously evolutionary learning methodology of tawhidi unity of knowledge.
The reason for this is that the existence of optimality and steady-state equilibrium makes all genres of economic systems untenable.The attenuating cost and production functions do not preserve their smooth structures according to the calculus of functional differentiation.Only learning curves in cost and output exist, causing non-existence of the marginal cost curve and marginal productivity measures.This was pointed out above.In the tawhidi perspective of continuous evolutionary learning with inter-causal participation and complementarities, the competition and methodological individualism concepts of self-interest that are found in mainstream and orthodox economics cannot exist.
Behavioral perspectives: Morality and ethics remain exogenous to mainstream and orthodox economic theory.Knowledge borne out of the monotheistic law of unity of knowledge is centrally poised in morality and ethics.Thus, for example, social justice and materialitylikewise, social capital and private capital ownershipare oppositely competed-for substitutes in mainstream economic theory of opportunity cost and scarcity of resources, except as exogenous ethical impacts change behavior though not continuously.Such resource injection occurs exogenously by external imposition.On the other hand, in the case of endogenous nature of knowledge, learning, and thereby of the continuity of moral and ethical consciousness, social and economic choices are treated to be complementary, participatory and continuously evolutionary by learning in unity of knowledge.Islamic behavioural attributes are first based on the consciousness of tawhid as Oneness of God and unity of the monotheistic law.This, in turn, needs the extraction of the ontological knowledge (theory of existence of being) from the Qurʾ an through the medium of the Sunnah and discourse among the learned ones on the Islamic nature of a purposive world-system.God, morality, ethics and the world-system: The oneness of God as belief, which is projected in the episteme of unity of knowledge in the tawhidi law, is the sole exogenous ontology of the tawhidi world-system.All other variables in the tawhidi world-system (ʿ alamīn) are paired by endogenous interrelations and circular causality of complementary relations (organic "pairing" as in the Qurʾ an).Thus, unlike the exogenous nature of morality and ethics in mainstream and orthodox economic theory, and then to the notion of ethics emerging from the a posteriori world of mind-matter, tawhidi methodology sets the emergence of ethics and morality in the monotheistic law of unity of knowledge and points out the opposite of differentiation.The extraction of such morality and ethics proceeds from the Qurʾ an via the Sunnah for inducing the paired causality of the world-system.The ontology of tawhidi law is then rendered to human discourse vis-à-vis the generality and details of diverse world-systems.These comprise the mind-matter dynamics, formalism, application and context.
The study of moral and ethical induction of Islamic behaviour and its representative inter-causal variables in the light of the tawhidi methodology of unity of knowledge invokes mathematical methods mostly of the topological type.Topology is the only branch of advanced mathematics that studies relations between non-dimensional categories.Differential calculus is sparingly used in relation to the knowledge variable.Time in the tuple comprising knowledge, space and time dimensions of tawhidi functional categories, remains simply a recorder of events, not a creator of anything.Knowledge remains the sole creator of events and change over the knowledge, space and time dimensions.TIE and its applications studied in this paper have the following definition: TIE is a scientific study of issues of economics in concert with all possible related fields that together interact to form organic influence on economic issues and events and viceversa.This encompassing scientific worldview of TIE is particularized in the metascience of the principal and sole axiom of all Islamic socio-scientific studies.It is the axiom of the monotheistic law of unity of knowledge in the good choices of life, which are choices derived from the purpose and objective of the Qurʾ anic lawmaq a Á sid al-Shariʿ ah.The same law rejects the bad choices of life.The two categories of goods and services are deciphered out of evolutionary learning according to the tawhidi law of unity of knowledge and the induced economic worldsystem with its moral, ethical, and systemic congeries.
The contrariety mentioned above exists between the nature of mainstream economics, its offspring in existing Islamic economics as presently understood on the one hand, and the tawhidi methodology applied to the generality and particularity of human cognition and experience on the other hand.An example of the particular is the emergence of the Qurʾ anic study of the economic issues of man and the universe.This paper formalizes the tawhidi methodological worldview in the rise of the corresponding economic and socio-scientific reasoning.Examples will be provided to bring out the contrariety between the opposing two worldviews of science, society and the economic world-system; and of morality, ethics and the world-system with particularity in economics.
An example here is of the problem of Islamic economics copying from orthodox and mainstream economic leaning.The example is that of acceptance of marginal rate of substitution or the opportunity cost idea in the existing idea of Islamic economics.Such marginalist idea leads to the substitution between social justice and economic efficiency as substitutes.Both of these are dear to Islamic epistemological reasoning.They are internalized in endogenous choice behavior in social preferences and their technological implications.In the tawhidi methodological worldview, morality and ethics are endogenously embedded in human inclinations by consciousness.They are not determined exogenously by costly external imposition, as by government and policing by the state.Humankind for the common good of well-being (ma Á sla Á hah) and purpose (maq a Á sid al-Sharīʿah) naturally accepts Sharīʿat al-tawhid.The maq a Á sid al-Sharīʿah is not a coerced law, as the Qurʾ an declares (10:32-33): Such is God your real Cherisher and Sustainer: Apart from Truth, what (remains) but error?Thus is the Word of thy Lord proved true against those who rebel: Verily they will not believe.
Teaching structure of TIE: for whom is this paper appropriate?This paper is recommended for students who have acquired a rigorous course of economics as science and with critical thinking.Indeed, TIE studied in the light of its epistemological foundations and as a scientific discipline should only be taken up after the student has completed introductory economics courses or, better, has done economics at the intermediate level.Indeed, the study of economics in the light of its epistemological issues is taught to international baccalaureate (IB) students as a general mandatory course.
The internet version of the IB theory of knowledge course states the significance of the theory of knowledge as follows: Theory of knowledge (TOK) is assessed through an oral presentation and a 1,600-word essay.It asks students to reflect on the nature of knowledge, and on how we know what we claim to know.TOK is part of the International Baccalaureate (IB) Diploma Programme (DP) core and is mandatory for all students.
For introduction to the theme of epistemology as scientific methodology, see Martin (2010): TOK aims to make students aware of the interpretative nature of knowledge, including personal ideological biases-whether these biases are retained, revised or rejected.It offers students and their teachers the opportunity to: reflect critically on diverse ways of knowing and on areas of knowledge; and consider the role and nature of knowledge in their own culture, in the cultures of others and in the wider world.
In addition, TOK prompts students to: be aware of themselves as thinkers, encouraging them to become more acquainted with the complexity of knowledge; and recognize the need to act responsibly in an increasingly interconnected but uncertain world.
TOK also provides coherence for the student by linking academic subject areas and transcending them.
It therefore demonstrates the ways in which the student can apply their knowledge with greater awareness and credibility.

Students' preparation
undergraduate courses in microeconomics, macroeconomics; undergraduate mathematics: set theory, calculus and statistics; and exegesis of the Qurʾ an and Sunnah.
There is no need to overwhelm the students with difficult areas all at once in the beginning; though an ensuing book ought to be a substantively rigorous work of TIE as the explication and application of the tawhidi epistemic core of the truly Islamic methodological worldview contra mainstream economics and Islamic economics in the mainstream garb.TIE would represent a rigorous course of a scientific and analytical treatment of economic issues in general and their Islamic perspective in particular.Its best slot for teaching is after the student has taken up introductory and intermediate courses in microeconomics and macroeconomics.At this level of maturity, the student would have also acquired mathematical preparation to understand the analytics and the terminology of TIE and the concepts of mainstream economic terms and theories.This will help the teacher and students to have a critical approach to the study of mainstream and neoclassical economics.There is no good reason for teaching any good course in Islamic economics at sub-standard levels below the levels comprising TIE.Any such course cannot ignore inclusion of a sound content of methodology; therefore, epistemology, ontology and phenomenology and the corresponding analytical understanding of what the true Islamic orientation in economics and socio-scientific project is as a meta-scientific worldview.Such is the holistic content of TIE.
Notes 1.The Qurʾ an (30:7) speaks of the concept of outer semblance as follows: "They know but the outer (things) in the life of this world; but of the End of things they are heedless." 2. On the aspect of pairing, the Qurʾ an (36:36) states: "Glory to Allah, Who created in pairs all things that the earth produces, as well as their own (human) kind and other things of which they have no knowledge."
