The purpose of this paper is to make people aware of organic corrosion inhibitors.

As it is a literature review paper, no specific method is used.

It has been found that plant extracts and oils show inhibition efficiency up to 98 percent, so it is certain that plant extracts and oils are effective corrosion inhibitors and can be successfully used at the industrial level.

Plant extracts and oils are also found to be non‐toxic, highly efficient, renewable and cheap. But less effort has been given towards the identification of which compound is active in the extract.

The paper shows detailed account of the inhibitors obtained from plants, which are used as natural corrosion inhibitors.

This paper aims to investigate the efficacy of grape pomace extract (GPE) as an eco-friendly vapor phase green inhibitor for corrosion of steel and assess the effect of the major compounds of extract on the inhibition efficiency.

The present study was carried out to identify the components present in the 2-propanol GPE by gas chromatography–mass spectrometry (GC-MS) analysis. Gravimetric, electrochemical impedance spectroscopy, potentiodynamic polarization, scanning electron microscopy and FTIR techniques were used to study the corrosion inhibitive.

GPE has inhibited mild steel corrosion in conditions of periodic condensation of moisture. The gravimetric measurement indicates that inhibition efficiency shows direct proportional relation with concentration of inhibitor. The GPE and main components acted as a mixed-type inhibitor with predominant cathodic effectiveness. Research limitations/implications. Because of the presence of large number of compounds in the extract, it becomes difficult to understand the most active compound responsible for inhibition. However, from gas chromatography, mass spectrometry and quantum data, the assumption has been made that the major compound of GPE is responsible for the inhibition activity.

The extract can be used in the temporary corrosion protection and is designed to prevent the corrosion of metal surfaces of equipment during transportation and storage.

GPE can be used as a potential source of ecofriendly corrosion inhibitor for steel corrosion.

The purpose of this paper is to study the ability of commercial tara powder to convert rust into iron tannate and evaluate their use as raw material for the formulation of water based rust converter.

Water-borne acrylic primers were formulated with tara powder and aqueous tara extract and applied on steel rusted by three different methods. The conversion of rusted steel by tara tannins was studied by X-ray diffraction spectroscopy, infrared spectroscopy and scanning electron microscopy. The acrylic primers, containing hydrolysable tannins, were coated with alkyd finish and were evaluated in comparison to commercial systems in accelerated corrosion tests. The corrosion inhibition effects of tara powder on mild steel in 0.1M NaCl were studied by DC electrochemical techniques.

Tara tannin converts rust to ferric tannate and increases the magnetite content of rusted steel. The water-based acrylic primer formulated with aqueous extract of tara, alkyd-coated finish, showed performance equivalent to pure alkyd system.

The chlorides content in the commercial tara powder can be screened the beneficial effect of hydrolysable tannins to convert rust. Furthermore, the water-based rust converter formulated with acrylic resin may be sensitive to salt contamination of rust.

Hydrolysable tannins from commercial tara powder have not been studied yet in its application to the development of rust converters. A water-based primer formulated with commercial tara powder developed for the effective treatment of rusted surfaces can be of interest as an environmentally friendly to current commercial approaches.

Najib Mahfuz is the first Arab‐language author to win the Nobel Prize in literature. Born in 1911 the son of a middle‐class Jamaliyah merchant, he became the most popular novelist in Egypt and the Arab countries.

During the past five decades, the role of government in most developed and developing countries has increased dramatically. Governments increased their provisions of social services and welfare. Furthermore, governments have become important producers of goods and services. In addition, by using a variety of fiscal and monetary instruments governments have attempted to manipulate and influence the economy. They have also sought to guide the development of the economy in the long run through the creation of economic infrastructure and institutions.

This paper aims to look into Islamic CSR, a literature domain that is rarely researched. The article has three goals. First, it provides an overview of the varying conceptualizations and paradigms underpinning CSR. Second, it presents an analogy relating commonalities and deviations between Islam and some of the basic international CSR paradigms. Third, it proposes a novel model of Islamic CSR based on the Islamic legislation (shar'iah) and applies it to an MNC with explicit application of Islamic CSR.

A case study of an explicitly Islamic‐abiding corporation has been investigated to test for the applicability of the proposal model. Semi‐structured interviews have been employed with both the CSR and the HR Heads in Egypt. In addition, various corporate communications have been also utilized in this study.

The research reflects upon international paradigms of CSR versus the Islamic one, highlighting its origins and providing an analogy among both perspectives. Also, a new model is developed and further put into action by the case study employed. Further research is needed to assess further the generalizability of the proposed model, especially with companies operating in Muslim‐majority countries and, hence, with potential implicit application of Islamic CSR.

Generalization of the model cannot be generated at this stage of the model development. Further large‐scale empirical research is needed for further development of the proposed model.

This research would prove useful for corporations operating in Muslim‐majority countries as well as for managers of companies interested in understanding the Islamic perspective on important contemporary world issues like CSR.

This article put forth a comprehensive Islamic CSR model based on the shari'ah while presenting the commonalities and differences between basic international CSR paradigms and the Islamic perspective on CSR.

This paper aims to investigate the influence of the determinants (pricing, type of structure, Shariah auditing, Shariah risk and Shariah documentation) and the sukuk legitimacy among Islamic financial institutions using a qualitative approach. The paper further explained the significance of the determinants on legitimacy, evaluated the relationship between sukuk characteristics and sukuk legitimacy and examined the moderating effect of Shariah Supervisory Board (SSB) on the relationship.

The study used a purposive sampling technique to select the target respondents required for the survey (semi-structured interview). This technique is applied by selecting members of SSBs among Islamic financial institutions. A total number of ten members are selected as the sample size for the study based on their experience and basic knowledge of Fiqh Al-Mua’malat and its application in Islamic financial institutions.

The findings revealed that the determinants have a significant impact on the sukuk legitimacy, meaning that there is a positive and significant relationship between the determinants and the sukuk legitimacy. In addition, this study indicates the empirical evidence of the moderating effect of SSB on the relationship between the determinants and the sukuk legitimacy.

This study has added to the literature by examining the determinants of sukuk legitimacy while evaluating the moderating effect of SSB on the relationship. Besides, this might add benefits to the numerous Islamic financial institutions relating to the amendment of its regulatory frameworks with the view to pushing the sukuk market investors to move toward asset-backed structure. In addition, the SSB in central banks must also focus its attention regarding the sukuk legitimacy and its application among the various Islamic financial institutions.

This study has added a new discussion to the body of knowledge, i.e. examining the sukuk legitimacy and its relationship with sukuk determinants; hence, an approach that is not widely discussed in the previous studies. Furthermore, conducting such research in the field of Islamic finance provides novelty in the literature among both emerging and developed economies including Malaysia. This is because to the best knowledge of the researchers, there was no empirical study (within the literature) that combined these variables and evaluated their empirical significance. Accordingly, this would enlighten the Islamic Ummah and propel the society’s intensity toward contributing to knowledge and might further provide clarification on the determinants and the sukuk legitimacy to prospective scholars, precisely on the moderating effect of SSB on the relationship between determinants and legitimacy of sukuk.

This study aims to investigate and propose the potential practice of hibah al-ʿumra as a Shari‘ah-compliant policy that would encompass the disbursement of death benefits and facilitate their smooth distribution among the projected beneficiaries of the family Takāful.

This study uses a qualitative approach. It conducts semi-structured interviews with different Takāful practitioners in Malaysia. This study also consulted a few Shari‘ah scholars regarding their opinions on the application of hibah al-ʿumra in disbursing family Takāful benefits. The thematic analysis is carried out to analyse qualitative data.

From both Shari‘ah and the relevant industry perspectives, the notion of hibah al-ʿumra has a great potential to disburse the family Takāful benefits to the Takāful participants or nominated beneficiaries. Given the conditional nature of hibah in Takāful, it is argued that there is a scope for imposing some conditions to make hibah al-ʿumra a life grant gift. This is expected to play a significant role in resolving the issues relating to the disbursement of family Takāful benefits among the beneficiaries, where it becomes irrevocable.

In the current practice of family Takāful, in the event of the recipient’s death or divorce, the application of absolute hibah results in the disbursement of Takāful benefits among undesirable beneficiaries. In contrast, in hibah al-ʿumra, it is expected that subject to a condition of withdrawal, its practice would help manage any unwanted situation if other potential beneficiaries are nominated upon signing the agreement at the outset.

This study is expected to contribute to help channel the family Takāful benefits into the desired beneficiaries being the proposed hibah al-ʿumra as a form of conditional hibah. Besides, this type of hiba can be treated as a solution in any adverse situation.

The purpose of this paper is to comprehensively discuss the issue of risk vis-à-vis the perpetuity restriction principle inherent in waqf (Islamic endowment). Specifically, it attempts to consolidate the axioms in both conventional and Islamic finance, such as the risk-return trade-off and al-ghunm bi al-ghurm (liability accompanies gain), with the perpetual nature of waqf. Overall, this paper attempts to find a resolution to the dilemma of perpetuity restriction inherent in cash waqf against the natural occurrence of the risk.

This paper is based on the secondary research methodology; past literature encompassing journal articles, books, relevant financial axioms, fatwas (Islamic rulings) and state enactments is critically reviewed to present its case. In regard to state enactments, only Malaysian state enactments have been used, thus restricting the study to the Malaysian case only.

This study contends that the dilemma of the perpetuity restriction and the natural occurrence of risk can be resolved through the integration of waqf risk management, especially concerning cash waqf, with the Islamic spiritual approach. By implementing standard operating procedures that inculcate awareness on waqf risk management and Islamic spirituality in waqf stakeholders (wāqif (donor), trustee and beneficiaries), the stakeholders may accept the reality of risk that is inevitable even after all efforts have been exhausted. In other words, the violation of perpetuity is exonerated given that mental faculties aligned with revealed texts have been exhaustively used beforehand.

Findings from this study may broaden the choice of investment avenues for waqf trustees while adhering to the perpetual restriction of waqf. More importantly, waqf trustees will not be forced to invest in interest-bearing securities or be involved in any usurious transactions just to obtain guaranteed returns and preserve the corpus of waqf.

This study offers a unique perspective on cash waqf risk management by re-analyzing the axioms and concepts of finance and waqf while observing the welfare of the beneficiaries.

This paper aims to analyse the Sharīʿah premises of waqf (Islamic endowment), followed by dilating on the nature of argumentation among the classical jurists on its rules and principles. The paper critically analyses the edifice of the applied juristic analogy of different early jurists in deriving various waqf doctrines. The objective of analysing the jurisprudential framework of waqf in its classical mould is to conceptualise the methods, mechanism and nature of juristic analogies in deriving the waqf principles. This analysis is critical to understand the scope of jurisprudential flexibility in modern awqāf.

The paper is an outcome of a library-based research. It uses the classical jurisprudential treatises of waqf with an aim to analyse the Sharīʿah basis of the institution, the premises of its key principles and the applied juristic analogy to derive the same. The paper covers the classical waqf books and treatises from the four Sunni schools of jurisprudence and uses a textual analysis method.

The paper finds that in its initial phase, the conceptual framework of waqf was not unanimously agreed by all jurists, rather its Sharīʿah permissibility remained critically disputed among them for a while. Though, the opinion of those jurists who approved the Sharīʿah-validity of waqf was to prevail in the later stage, disagreement persisted with reference to its necessary features and defining criteria. It is found that in the classical waqf literature, two most disputed aspects of waqf jurisprudence constituted the requirements for completion of a waqf and its ownership status.

This study neither covers the historical contribution of waqf among the Muslim societies nor touches on the empirical aspects of modern waqf. Rather, the focus of the study is limited to analysing the classical jurisprudential discourse of waqf and distillation process of its rulings.

The objective of analysing the classical juristic discourse of waqf is to underline the premises of classical juristic analogy in determining the framework of fiqh al-awqāf (jurisprudence of waqf) in its classical permutations and to learn how to adopt a similar approach for deduction of new waqf rulings.

This paper adds original value to the body of waqf literature for analysing the classical waqf rulings distillation process along with examining the methods and mechanism of juristic analogy.
