Abstract

Purpose

The purpose of this paper is to unearth the factors inhibiting the development of zakat (the Islamic obligatory alms) and waqf (endowment) institutions in Northern Nigeria, with the aim of proffering appropriate solutions.

Design/methodology/approach

This paper uses a qualitative research methodology whereby data was sourced from relevant stakeholders in Northern Nigeria. To select the appropriate interviewees, maximum variation and homogenous purposeful sampling techniques were used.

Findings

The findings of the paper show that zakat and waqf institutions in Northern Nigeria have not achieved their inherent Sharīʿah objectives because members of the public have little or no trust or confidence in the institutions. Also, the potential zakat payers and waqf donors dislike political office holders’ involvement in the appointment of the institutions’ administrators. Finally, the administrators lack adequate managerial and administrative knowledge of the two institutions.

Research limitations/implications

The current research focusses on causes of low performance of zakat and waqf institutions solely in Northern Nigeria. It is envisaged that subsequent researchers may conduct research on the possibility of having a federal law that will strengthen the overall establishment and development of zakat and waqf in Nigeria. This will affect both Muslim-majority and Muslim-minority communities.

Originality/value

This paper represents a referenceable work in the field of zakat and waqf in Northern Nigeria, as it uses an approach that sources primary data in the form of participants’ point of view instead of relying on literature or document analysis. It is not a mere theoretical study of the literature but an empirical investigation of the problem.

Abstract

Purpose

A generalization of Ascoli–Arzelá theorem in Banach spaces is established. Schauder's fixed point theorem is used to prove the existence of a solution for a boundary value problem of higher order. The authors’ results are obtained under, rather, general assumptions.

Design/methodology/approach

First, a generalization of Ascoli–Arzelá theorem in Banach spaces in Cn is established. Second, this new generalization with Schauder's fixed point theorem to prove the existence of a solution for a boundary value problem of higher order is used. Finally, an illustrated example is given.

Findings

There is no funding.

Originality/value

In this work, a new generalization of Ascoli–Arzelá theorem in Banach spaces in Cn is established. To the best of the authors’ knowledge, Ascoli–Arzelá theorem is given only in Banach spaces of continuous functions. In the second part, this new generalization with Schauder's fixed point theorem is used to prove the existence of a solution for a boundary value problem of higher order, where the derivatives appear in the non-linear terms.

Abstract

Purpose

The purpose of this paper is to focus on the removal of hexavalent chromium [Cr(VI)] from wastewater by using activated carbon-supported Fe catalysts derived from walnut shell prepared using a wetness impregnation process. The different conditions of preparation such as impregnation rate and calcination conditions (temperature and time) were optimized to determine their effects on the catalyst’s characteristics.

Design/methodology/approach

The catalyst samples were characterized using thermogravimetric analysis, scanning electron microscopy and Fourier transform infrared spectroscopy. The adsorption of Cr(VI) by using using activated carbon supported Fe catalysts derived from walnut shell as an adsorbent and catalyst was investigated under different adsorption conditions. The parameters studied were contact time, adsorbent dose, solution pH and initial concentrations.

Findings

Results showed that higher adsorption capacity and rapid kinetics were obtained when the activated walnut shell was impregnated with Fe at 5 per cent and calcined under N2 flow at 400°C for 2 h. The adsorption isotherms data were analyzed with Langmuir and Freundlich models. The better fit is obtained with the Langmuir model with a maximum adsorption capacity of 29.67 mg/g for Cr(VI) on Fe5-AWS at pH 2.0.

Originality/value

A comparison of two kinetic models shows that the adsorption isotherms system is better described by the pseudo-first-order kinetic model.

Abstract

Keberkesanan penyampaian sesuatu maklumat memerlukan individu, alat mahupun saluran yang unggul dan bersesuaian. Usaha ini haruslah dirancang dan dipertimbangkan dengan teliti oleh pihak tertentu agar setiap apa yang ingin disampaikan dan dilaksanakan itu dapat diberigakan dengan mudah dan berkesan. Dari itu, penggunaan bahasa retorik dilihat sebagai batu loncatan yang memberikan keyakinan dan tahap keberkesanan yang tinggi bagi sesebuah wacana yang disampaikan tersebut. Kewibawaan retorik sebagai seni yang mempengaruhi bukan sahaja berperanan untuk memperkukuhkan kekuasaan mahupun mempengaruhi fikiran dan emosi orang lain namun sebaliknya mampu menstimulasikan keseimbangan hubungan sosial yang terbentuk melalui sistem pemerintahan sesebuah negara. Melalui penyelidikan ini, setiap ciri khas retorik dapat diketengahkan dengan menghuraikan peranan dan fungsi-fungsi yang dimainkan oleh jenis-jenis retorik dalam penulisan sesebuah wacana. Hal ini khusus bagi mengilustrasikan idea, gagasan mahupun suatu fakta terhadap sesuatu pendekatan dengan cara yang kreatif dan terbaik. Di samping itu, keutamaan bagi penerapan bahasa retorik dalam perutusan kerajaan seharusnya dapat diperkasakan sewajarnya dengan menjadikannya sebagai anjakan paradigma ke arah perpaduan dan nilai kesaksamaan dalam masyarakat. Justeru, kajian ini memanfaatkan Teori Retorik Moden oleh Enos dan Brown (1993) sebagai landasan utama dalam menganalisis sejumlah 20 perutusan rasmi berkaitan jangkitan covid-19 di Negara Brunei Darussalam. Berdasarkan pemerhatian dan penganalisisan yang dijalankan, hanya empat jenis retorik yang diaplikasikan dalam wacana tersebut. Kesimpulan statistik merangkumi 34% teknik pendedahan, 30% teknik penerangan, 33% teknik pemujukan dan hanya 3% bagi teknik penghujahan. Dapatan penyelidikan ini membuktikan bahawa penggunaan bahasa retorik dalam perutusan rasmi kerajaan adalah amat penting dalam memperkukuhkan sistem pemerintahan negara serta mampu melestarikan cara hidup yang relevan dan berkualiti.

The effectiveness of delivering information requiresindividuals, tools or channels that are superior and appropriate. This effort must be planned and considered carefully so that everything that is to be conveyed and implemented can be conveyed easily and effectively. Therefore, the use of rhetorical language is regarded as a stepping stone that provides confidence and a higher level of effectiveness. `Rhetoric as an influential art not only plays a role in strengthening power or influencing the thoughts and emotions of others but also stimulate sthe balance of social relations. Through this research, each rhetorical feature is highlighted to discuss its role and functions in the discourse. Using Enos and Brown’s Modern Rhetorical Theory (1993), a total of 20 official conferences on the latest developments of the spread of covid-19 infection were discussed. Findings have shown that there were four main types of rhetoric, i.e. Statistical conclusions which include 34% of expository techniques, 30% of descriptive, 33% of persuasion and only 3% for argumentation techniques. This also implies that rhetoric language is very important in ensuring the dissemination of knowledge among the institution and people is effective and and transparent.

Abstract

Gema Dari Menara (1968) was intended as a mode of da’wah (the propagation of Islamic teachings) in response to the situation faced by the local community in Brunei at that time. Following its status as a medium of disseminating the Islamic values, the film embodies Islamic teachings that guide Bruneian Muslims to fully embrace Islam. This current study aims to unravel the meaning of the Islamic value of Amar Ma’ruf Nahi Mungkar (enjoining good and forbidding wrong) that is strongly depicted in the film and perceived as the enlightening Islamic value from the film. Therefore, this study examines the extent of the manifestation of Amar Ma’ruf Nahi Mungkar in the film. It is found that the portrayal of da’wahism using Amar Ma’ruf Nahi Mungkar is imbued in education, social interaction, clothing, and one’s upbringing which is the most influential factor. By applying the Islamic requisites, the scenario and sentiments in the film also encourage the audience to ponder upon the cause and effect of the characters’ actions and deeds.

Abstract

Purpose

This study argues that in order to address the problems associated with the modern market economy at their core, such as persistent poverty, growing inequality and environmental degradation, it is imperative to re-assess the well-being and moral philosophy underpinning economic thinking. The author attempts to offer a preliminary way forward with reference to the Islamic intellectual tradition.

Design/methodology/approach

This study employs content analysis of classical and contemporary Islamic texts on human well-being and economic ethics to derive a conceptual well-being model. The paper is structured in four sections: section one provides an overview of relevant secondary literature on moral economic approaches; section two outlines the main well-being frameworks; section three discusses the concept of human well-being in Islam informed by the Islamic worldview of tawḥīd, the Islamic philosophy of saʿādah, and the higher objectives of Islamic Law (maqās.id al-Sharīʿah); and finally, section four discusses policy implications and next steps forward.

Findings

A conceptual model of human well-being from an Islamic perspective is developed by integrating philosophical insights of happiness (saʿādah) with an objective list of five essential goods: religion (Dīn), self (Nafs), intellect ('Aql), progeny (Nasl) and wealth (Māl) that correspond to spiritual, physical and psychological, intellectual, familial and social, and material well-being, respectively.

Research limitations/implications

Further research is needed to translate this conceptual model into a composite well-being index to inform policy and practice.

Practical implications

This model can be used to review the performance of the Islamic finance sector, not solely in terms of growth and profitability, but in terms of realising human necessities, needs and refinements. It can also provide the basis for the Organisation of Islamic Co-operation (OIC) countries to jointly develop a well-being index to guide national and regional co-operation. More generally, this study highlights the need for research in Islamic economics to be more firmly rooted within Islamic ontology and epistemology, while simultaneously engaging in productive dialogue with other moral schools of economic thought to offer practical solutions to contemporary challenges.

Originality/value

This study offers three aspects of originality. First, by outlining well-being frameworks, it highlights key differences between the utilitarian understanding of well-being underpinning modern economic theory and virtue-based understandings, such as the Aristotelian, Christian and Islamic approaches. Second, it provides a well-being model from an Islamic perspective by integrating the Islamic worldview of tawḥīd, the Islamic philosophy of saʿādah, and the higher objectives of Islamic Law (maqāṣid al-Sharīʿah). Third, it proposes an ethical framework for informing economic policy and practice.

Abstract

Purpose

Over the last decade, investments in green energy companies have witnessed noticeable growth rates. However, the glacial pace of the world economic restoration due to COVID-19 pandemic placed a high degree of uncertainty over this market. Therefore, this study investigates the short- and long-term relationships between COVID-19 new cases and WilderHill New Energy Global Innovation Index (NEX) using daily data over the period from January 23, 2020 to February 1, 2023.

Design/methodology/approach

The authors utilize an autoregressive distributed lag bounds testing estimation technique.

Findings

The results show a significant positive impact of COVID-19 new cases on the returns of NEX index in the short run, whereas it has a significant negative impact in the long run. It is also found that the S&P Global Clean Energy Index has a significant positive impact on the returns of NEX index. Although oil has an influential effect on stock returns, the results show insignificant impact.

Practical implications

Governments have the chance to flip this trend by including investment in green energy in their economic growth stimulation policies. Governments should highlight the fundamental advantages of investing in this type of energy such as creating job vacancies while reducing emissions and promoting innovation.

Originality/value

First, as far as the authors are aware, the authors are the first to examine the effect of oil prices on clean energy stocks during COVID-19. Second, the authors contribute to studies on the relationship between oil prices and renewable energy. Third, the authors add to the emerging strand of literature on the impact of COVID-19 on various sectors of the economy. Fourth, the findings of the paper can add to the growing literature on sustainable development goals, in specific the papers related to energy sustainability.
