Ferrofluids are aqueous or non-aqueous solutions with colloidal particles of iron oxide nanoparticles with high magnetic characteristics. Their magnetic characteristics enable them to be controlled and manipulated when ferrofluids are exposed to magnetic fields. This study aims to inspect the features of unsteady stagnation point flow (SPF) and heat flux from the surface by incorporating ferromagnetic particles through a special kind of second-grade fluid (SGF) across a movable sheet with a nonlinear heat source/sink and magnetic field effect. The mass suction/injection and stretching/shrinking boundary conditions are also inspected to calculate the fine points of the features of multiple solutions.

The leading equations that govern the ferrofluid flow are reduced to a group of ordinary differential equations by applying similarity variables. The converted equations are numerically solved through the bvp4c solver. Afterward, study and discussion are carried out to examine the different physical parameters of the characteristics of nanofluid flow and thermal properties.

Multiple solutions are revealed to happen for situations of unsteadiness, shrinking as well as stretching sheets. Greater suction slows the separation of the boundary layers and causes the critical values to expand. The region where the multiple solutions appear is observed to expand with increasing values of the magnetic, non-Newtonian and suction parameters. Moreover, the fluid velocity significantly uplifts while the temperature declines due to the suction parameter.

The novelty of the work is to deliberate the impact of mass suction/injection on the unsteady SPF through the special second-grade ferrofluids across a movable sheet with an erratic heat source/sink. The confirmed results provide a very good consistency with the accepted papers. Previous studies have not yet fully explored the entire analysis of the proposed model.

Flow induced by rotating disks is of great practical importance in several engineering applications such as rotating heat exchangers, turbine disks, pumps and many more. The present research has been freshly displayed regarding the implementation of an engine oil-based Casson tri-hybrid nanofluid across a rotating disk in mass and heat transferal developments. The purpose of this study is to contemplate the attributes of the flowing tri-hybrid nanofluid by incorporating porosity effects and magnetization and velocity slip effects, viscous dissipation, radiating flux, temperature slip, chemical reaction and activation energy.

The articulated fluid flow is described by a set of partial differential equations which are converted into one set of higher-order ordinary differential equations (ODEs) by using convenient conversions. The numerical solution of this transformed set of ODEs has been spearheaded by using the effectual bvp4c scheme.

The acquired results show that the heat transmission rate for the Casson tri-hybrid nanofluid is intensified by, respectively, 9.54% and 11.93% when compared to the Casson hybrid nanofluid and Casson nanofluid. Also, the mass transmission rate for the Casson tri-hybrid nanofluid is augmented by 1.09% and 2.14%, respectively, when compared to the Casson hybrid nanofluid and Casson nanofluid.

The current investigation presents an educative response on how the flow profiles vary with changes in the inevitable flow parameters. As per authors’ knowledge, no such scrutinization has been carried out previously; therefore, our results are novel and unique.

This study aims to examine the factors of implementing istibdal waqf and generating cash waqf funds through istibdal in Penang. This study was based on the previous problem statements, stating that waqf property could not be developed due to lack of cash funds. This has allowed the study to explore the factors for implementing istibdal waqf property and the extent to which the istibdal method can generate cash waqf funds in Penang.

This study adopted a qualitative method by conducting semi-structured interviews to achieve its research goals. Semi-structured interviews were conducted to comprehensively understand the current practice on istibdal cases in Penang State Islamic Religious Council (MAINPP) through official institutions concerned with waqf management practices in Penang. This research relied on purposive sampling to select the informants. It is a sampling strategy to select the informants in advance based on the research question. To achieve the purpose of this study, two officers from MAINPP were selected based on their working experience and specialisation criteria. As a result, several themes were successfully defined from the interview data before being analysed based on the content analysis method.

The results present three istibdal implementation processes outlined by MAINPP, namely, the istibdal implementation process for waqf land involved in the acquisition by state authorities (PBN), non-productive waqf land and istibdal applications from certain parties. The results also reveal two factors in implementing istibdal in Penang: the acquisition of waqf land by PBN and the application of istibdal for cemeteries by the Islamic Centre of Universiti Sains Malaysia. From the point of cash fund generation, no case of istibdal implementation records the generation of cash funds to MAINPP. Thus, this study ends with proposals for improving the process and implementing istibdal in Penang to generate cash funds to help MAINPP manage waqf properties.

The study only focused on implementing factors and generating cash waqf funds through istibdal in Penang. At the same time, it can be expanded to other states like Terengganu, Johor and Kelantan. This study only interviewed officers who manage matters related to the affairs of waqf properties. Therefore, it is believed that the study can be extended to other respondents, such as experts in cash fund generation investments and others.

This study proposed improvements to the policy and practice of istibdal waqf property to MAINPP after the shortcomings were identified throughout this study. If improved, these proposals will significantly impact the waqf properties involved in implementing istibdal, where it can generate cash and ensure the constant economic value of waqf properties.

This study has great implications for society through the development of a cash waqf fund that can provide great benefits to the needy, in addition to increasing funds for the welfare expenditure of Muslims through rental income, investment and development. Progress and significant impact on waqf property can provide a high indicator of the efficiency of an organisation in managing waqf property. This can attract the interest of the public, especially the wealthy, to always fulfil welfare through the waqf mechanism and share the wealth with the needy.

This study contributes to comprehensive field data on the implementation of istibdal in Penang. The data analysis results are significant to be used by the waqf property management.

The study was collected during Time lag (1) and Time lag (2) from 156 to 216 bank employees, respectively. The study applied two types of analysis, to comprehend the impact of COVID-19 on employees, descriptive analysis and the partial least squares (PLS) are used.

The study's findings focused mainly on the influence of COVID-19 in Jordanian banks on employee innovative performance (EIP) due to pandemic, in addition to its effect on environmental responsibility engagement (ERE). The findings indicated a positive significant relationship between the variables. Meanwhile, employee engagement (EE) mediated the effect between the exogenous and endogenous variables.

The current research provide light on the value of employees' innovative performance and banks' commitment to environmental responsibility for those working in the banking industry, particularly during a pandemic. The findings have significant ramifications for the banking industry and in raising employee engagement.

Liquidity is a primary concern for businesses. The purpose of this study is to understand the impact of the collaborative liquidity management within the supply chain. Larger firms prescribe favorable trade terms in the transactions and do not engage in value chain vision sharing with their smaller counterparts. Smaller firms encounter challenges with liquidity and often face the risk of bankruptcy. Such practice can threaten the entire supply chain. Instead, collaborative liquidity management can offer a win–win scenario to both parties. In that case, what are the benefits of implementing a collaborative liquidity management approach across the value chain, and what is the reward?

The authors selected key liquidity metrics that matter most to the organizations from a cohort of 307 firms from the Indian automobile industry for 10 years (2012–2021). The authors classified the businesses into five distinct revenue-based categories. They emphasized the importance of expanded supply chain finance adoption and demonstrated how collaborative liquidity management strategies boosted return on assets.

The research confirms the tangible benefits of greater adoption of supply chain finance in realizing supply chain members’ shared vision. The authors challenged the age-old practice of power-based relationships in the supply chain. They recommended a win–win scenario through practical cooperation and increased adoption of SCF by value chain members.

Existing research predominantly focuses on dyadic relationships and is restricted to Europe and China. According to the authors, no comprehensive investigation has been conducted in India. This application of simulation techniques to improve the liquidity performance of companies in developing economies is innovative.

Sharia-compliant financial technologies (Islamic fintech) are becoming increasingly popular among Muslims and non-Muslims. As the Islamic fintech landscape continues to grow and transform, it is crucial to understand the factors that influence the acceptance or adoption of Islamic fintech services from the past literature. Therefore, this paper aims to conduct a systematic literature review (SLR) to investigate and compile factors that could influence a user to adopt Islamic fintech.

The current study adopted the systematic literature review approach using Preferred Reporting Items for Systematic Reviews and Meta-Analyses technique to examine research on Islamic fintech adoption. A set of inclusion criteria was applied to filter out irrelevant documents and ensure the selection of only the most relevant ones. The criteria were limited to quantitative journals published in English between 2012 and 2022, as identified in Scopus outlets.

Despite the existence of various theoretical frameworks, the technology acceptance model and Unified Theory of Acceptance and Use of Technology 2 frameworks have gained prominence as the most frequently applied frameworks in examining Islamic fintech adoption. In addition, trust is the most important self-developed construct for the adoption of Islamic Fintech.

The current study does not segregate the intention, actual usage and retention, as the author is interested in understanding the overall adoption of Islamic fintech services. To obtain more specific analysis results, future research could potentially separate the three types of adoption exposure, i.e., consumer acceptance, intention and retention. Next, future studies can also expand their analysis and gain a better understanding of the research topic by exploring alternative data sources such as Web of Science, ERA or JSTOR.

To the best of the author’s knowledge, this study makes a significant contribution to the literature by providing the first systematic literature review of factors influencing fintech adoption from an Islamic perspective.

Islamic financial institutions (IFIs) in Malaysia continue to promote Shari‘ah-compliant business and transactions. As a result, the governors have a lot to think about before issuing any fatwa or ordinance, which impacts the majority of Malaysians. Nevertheless, the point of views from the governors have not been highlighted much. This research seeks to investigate the extent to which the conception of al-Siyasah al-Shar‘iyyah is embraced by Shari‘ah committees’ leadership roles within IFIs. The importance of al-Siyasah al-Shar‘iyyah in decision-making makes abandoning the Shari‘ah principle untenable and its significant role for IFIs in Malaysia cannot be overstated. It serves as a crucial tool for decision-making by authorities and governors.

The objectives of this research are attained by examining diverse sources obtained through library research, encompassing books, journals, newspapers, websites and reports. In addition, to use an analytical method to assess the role of al-Siyasah al-Shar‘iyyah in IFIs pratical, the authors collect information through interviews with five participants actively engaged in Shari‘ah committees within financial institutions, both directly and indirectly.

The research paper concludes that al-Siyasah al-Shar‘iyyah holds significance for Shari‘ah committees in IFIs when providing legal opinions. In situations where existing madhhab-based laws prove insufficient for addressing a particular issue, the Shari‘ah committees will autonomously engage in new ijtihad to ensure effective resolution of the matter.

The implication that could have been resulted from this study is to indicate how Shari‘ah committees in IFIs structuring a set of rules and regulations embedded by al-Siyasah al-Shar‘iyyah elements to produce maṣlaḥaḥ for the ummah. This perspective is barely discussed in depth as Malaysia has unanimous scholars who work in this area. Thus, the authors attempt to bring the discussion academically and express the point of view from governors’ perspective.

In the Malaysian context, where Islamic banks and financial institutions are overseen by Shari‘ah committee members and the Central Bank of Malaysia, this study delves into the practical experiences of governors in carrying out the responsibilities of al-Siyasah al-Shar‘iyyah within the decision-making process. The objective is to investigate the perspectives of Shari‘ah committees when they encounter scenarios where prevailing madhhab opinions prove inadequate in addressing contemporary issues within the country.

Food waste, a global conundrum with adverse socioeconomic and environmental implications, occurs when more money is spent on food during occasions akin to Ramadan. This study examines the moderating role of antecedents (festive experience, nostalgic food memory, perceived scarcity, and religiosity) to understand the impacts of excessive food buying on Ramadan food waste.

A cross-sectional survey was performed with a self-administered questionnaire using Google Forms to gather data on social media. Notably, 349 valid responses were analysed via Partial Least Squares Structural Equation Modelling (PLS-SEM) with SmartPLS 4 for model development and hypothesis testing.

Festive experience, nostalgic memory, and perceived food scarcity could explain excessive buying behaviour. In this vein, excessive food buying contributed to Ramadan food waste. Meanwhile, religiosity was found to moderate excessive food-buying behaviour.

The empirical findings offered useful insights for practitioners and policymakers to implement optimal marketing strategies and interventions that improve responsible consumption and minimise food waste.

This study provided a sound understanding of consumer buying behaviour during Ramadan regarding food waste and overconsumption. The current work delineated the role of descriptive, injunctive norms and cognitive dissonance in shaping buying behaviour during Ramadan.
