This study aims to provide a bibliometric analysis of 1,104 journal articles to explore the multifaceted research field of Islamic finance and banking, explicitly emphasising the impact of the COVID-19 pandemic.

Insights into the evolving trends and dynamics within the academic discourse are presented.

The research highlights different patterns and collaborative networks through co-authorship, co-occurrence and thematic map analyses. Prior to the pandemic, research focused primarily on customer satisfaction and compliance with Shariah principles. However, the pandemic heralded an increased discourse on sustainability, fintech and the financial crisis.

This review describes the prevailing academic terrain and identifies potential avenues for future research, particularly those that examine the socio-economic impact of the pandemic within the context of Islamic finance and banking.

Prominent author such as M. Kabir Hassan, leading institution such as the International Islamic University Malaysia and esteemed journal such as the International Journal of Islamic and Middle Eastern Finance and Management have been instrumental in shaping academic discussions and creating synergies in research. Moreover, Malaysia’s strong commitment to spatial research, evidenced by its robust global collaborations, underscores its pioneering role in the academic world of Islamic finance and banking.

The use of social media for sustainable information is important since it has the potential to influence people’s intentions and behaviour towards sustainability. As previous studies on social media and sustainable development have primarily focussed on Western viewpoints, this study presents a comprehensive Asian perspective by investigating the impact of social media on sustainable intention and behaviour amongst Malaysian and Indonesian undergraduate university students.

A campus-wide online survey was conducted with 953 students from Malaysia and Indonesia. The researchers collected data through an online questionnaire and a two-week quantitative survey of undergraduate students in Malaysia and Indonesia. Quantitative data were analysed by SmartPLS software and comparative studies were conducted.

The result of the survey indicated that Facebook and Instagram were mainly used by Malaysian students to obtain and communicate about sustainability information, whilst Instagram was mainly used by Indonesian students. The findings also discovered that social media usage and social media effectiveness and usefulness are statistically significant predictors of sustainable intention amongst the students in Malaysia and Indonesia. Sustainable intention is also a statistically significant predictor of sustainable behaviour amongst the students. Additionally, this study also found that Malaysian students appeared to have a high level of the effect of sustainable intention on sustainable behaviour and the effect of the effectiveness and usefulness of social media to sustainable intention compared to Indonesian students. On the contrary, their use of social media related to sustainable behaviour was relatively low compared to Indonesian students.

Overall, the findings can contribute to the presently scant empirical works that focus on social media’s influence on sustainability and sustainable development. Furthermore, the findings contribute to the growing body of knowledge related to sustainability communication and sustainable education, particularly in terms of the use of social media in the learning and teaching process. Future research could focus on studying postgraduate students and university students from other Asian countries. Moreover, using qualitative methods like in-depth interviews or focus group discussion and applying other theories might unveil further results.

The purpose of the study is to analytically as well as numerically investigate the weight of throughflow on the onset of Casson nanofluid layer in a permeable matrix. This study examines both the marginal and over stable kind of convective movement in the system.

A double-phase model is used for Casson nanofluid, which integrates the impacts of thermophoresis and Brownian wave, whereas for flow in the porous matrix the altered Darcy model is occupied under the statement that nanoparticle flux is disappear on the boundaries. The resultant eigenvalue problem is resolved analytically as well as numerically with the help of Galerkin process with the Casson nanofluid Rayleigh–Darcy number as the eigenvalue.

The findings revealed that the throughflow factor postpones the arrival of convective flow and reduces the extent of convective cells, whereas the Casson factor, the Casson nanoparticle Rayleigh–Darcy number and the reformed diffusivity ratio promote convective motion and also decrease the extent of convective cells.

Controlling the convective movement in heat transfer systems that generate high heat flux is a real mechanical challenge. The proposed framework proved that the use of throughflow is one of the most important ways to control the convective movement in Casson nanofluid. To the best of the authors’ knowledge, no inspection has been established in the literature that studies the outcome of throughflow on the Casson nanofluid convective flow in a porous medium layer. However, the convective flow of Casson nanofluid finds many applications in improving heat transmission and energy efficiency in a range of thermal systems, such as the cooling of heat-generating elements in electronic devices, heat exchangers, pharmaceutical practices and hybrid-powered engines, where throughflow can play a significant role in controlling the convective motion.

The world today is heavily controlled by the content available on the internet, where a one-star rating gain may work wonders for a company and a one-star rating decline can cause huge damage. Online booking platforms provide more freedom, privacy and contact with experienced travelers than physical hotel booking. The study identifies the factors shaping travelers' online hotel booking intention (OHBI).

We utilized structural equation modeling (SEM) to expand the horizons of the technology acceptance model (TAM) and stimulus-organism-response (SOR) framework in the hospitality sector. The results are based on the data collected from 705 travelers who made online hotel reservations.

The findings demonstrate that online reviews, hotel website quality and hotel website convenience quotient favorably shape prospective tourists' perceived trust, magnifying their inclination to book a hotel online. Website convenience quotient and trust partially mediate the association between the constructs. In addition, the linkage between perceived trust and OHBI is strengthened by promotional offers but weakened by perceived risk.

Our findings provide several important implications for hotel managers, prospective travelers, hotel owners, website developers, policymakers, hotel employees, the local community and competitors to expedite the growth of the Indian hotel industry.

The literature reveals that website convenience quotient, perceived trust and promotional offers have not received enough attention in the hospitality industry and warrant attention. Our study strives to broaden the scope of the TAM and SOR models to better understand these constructs in the backdrop of the Indian hospitality sector. The study also examines how promotional offers and perceived risk influence the linkages between the underlying constructs.

This paper aims to propose a Shariah-compliant multi-period fuzzy portfolio optimization model that accounts for Shariah compliance through purification processes and incorporates various Shariah constraints, including sustainability constraints. This model aims to ensure both ethical alignment and robust portfolio management while navigating modern financial complexities and fostering responsible and sustainable investment practices.

The methodology involves a dynamic programming method to solve the proposed program, with returns of the assets assumed to be trapezoidal fuzzy variables. This approach allows for the quantification of portfolio return and risk by the possibilistic mean and semivariance of the fuzzy returns, respectively. A numerical study based on real stock market data tests the efficiency of the proposed algorithm.

The research showcases the model’s effectiveness in managing Shariah-compliant portfolios under financial uncertainties and supports the importance of incorporating ethical and sustainability constraints in investment decisions. It highlights the capability of the proposed model to offer a structured approach to ethical investing within the Islamic finance framework.

While the paper provides a solid foundation for Shariah-compliant portfolio optimization, it acknowledges the complexity and computational demands of the model. Future research could explore simplifying the model without compromising its ethical and Shariah-compliant principles.

This work introduces a novel integration of Shariah compliance with fuzzy portfolio optimization techniques, addressing the need for dynamic, ethical investment strategies in Islamic finance. The incorporation of purification processes and sustainability constraints into a fuzzy portfolio optimization model represents a unique contribution to the field.

This study aims to investigate the evolving travel intentions of tourists in the aftermath of the relaxation of international mobility restrictions in 2022. It aims to understand how the concept of “revenge travel” – travelling with the intent to make up for lost time during crisis periods – impacts tourists' travel intentions in the post-crisis era.

Employing a quantitative approach, the study uses Structural Equation Modelling (SEM). Data were collected through a survey of 320 respondents in 2022. This methodology enables a comprehensive understanding of travel intentions, including motivations, perceptions of destination safety and the influence of revenge travel.

The findings reveal that revenge travel is a significant predictor of travel intentions post-crisis. The results indicate that tourists are less concerned with health and safety and are more driven by the desire to compensate for lost travel opportunities. This shift suggests that travel intentions in the post-crisis era are not predominantly fear-induced. The study also offers insights into how these intentions can inform the recovery and sustainable planning of the tourism industry.

This paper recognises the impact of revenge travel on travel intentions following the lifting of crisis-related mobility restrictions. It provides novel insights into tourists' post-crisis travel behaviour, extending the understanding of travel motivations in extraordinary circumstances. The findings are valuable for tourism practitioners and researchers, offering guidance for future tourism development and marketing strategies within a post-crisis context.

The purpose of this study is to examine the factors that influence people’s behaviour in paying zakat, explore their perceptions of the institutions, examine the factors that influence their trust and analyse the impact of trust on their behaviour in paying zakat to the institutions.

A questionnaire was distributed to 740 potential Zakat payers in the Federal Territory, Malaysia. In designing the questionnaire, a systematic literature review, focus group discussions and pilot study were conducted. Descriptive analysis and partial least squares structural equation model were used with SmartPLS software.

The result shows that trust, intention to pay zakat and age of the respondents have statistically significant impacts on people’s behaviour to pay zakat through institutions. Intention to pay zakat is influenced by attitudes, subjective norms and perceived behavioural control. In addition, the main common concerns expressed were lack of awareness of the importance of paying zakat, lack of transparency in zakat administration, especially in collection and distribution, and inefficiency in administration and distribution. Moreover, trust in the institutions could be established if the institution is able to fulfil its mission of collecting and distributing zakat to the entitled Asnaf and improve their welfare, as trust not only has a direct impact on people’s behaviour, but also strengthens people’s intention and influences their behaviour to pay zakat to the institutions.

This study focuses on a specific geographical area and zakat institution; hence, the study’s generalisability is limited. The use of self-reported and cross-sectional data may introduce bias and fail to capture the dynamic change of trust, intention and behaviour across time. The proposed solution of leveraging digital platforms may provide numerous hurdles and obstacles for adoption by the zakat institution.

This study shows the significant role of trust in influencing people’s intentions and behaviour in supporting organisations. Therefore, it can serve as an indicator of the performance or success of a particular institution. Thus, there is a need to find strategies to gain people’s trust by improving their ability, integrity and benevolence in performing their tasks.

This study aims to investigate differences between Islamic and conventional banks in Pakistan with respect to their operational efficiency, liquidity risk and asset quality. Importantly, in addition to full-fledged Islamic and conventional banks, this study also investigates a more recently emerged breed of hybrid banks, i.e. Islamic divisions of conventional banks.

Data for the period 2011–2020 was collected from financial reports of all full-fledged Islamic banks (5), Islamic banking divisions of conventional banks (8) and conventional banks (20) in Pakistan. Logistic regressions were designed to test the proposed hypotheses.

The findings suggest that full-fledged Islamic banks are operationally less efficient and experience higher liquidity risk than conventional banks. However, the asset quality of Islamic banks is better than that of conventional banks. Next, in the robustness analysis, the authors extended the sample size by adding the Islamic divisions (window) of the conventional banks; they found almost the same result except for efficiency which turned out to be non-significantly related to bank type.

The findings are beneficial for investors, depositors, consumers and bank management in understanding the financial features of such as efficiency, liquidity and liquidity risk that separate Islamic banks from conventional banks.

The findings of this study present a clear picture to bankers and practitioners about some financial features of banking systems and depict that Islamic banks are in need to improve their liquidity risk management practices to compete with conventional banks.

The purpose of this study is to propose and develop a zakat model for digital assets from the Sharīʿah perspective.

This research adopts a qualitative research method while studying the literature thoroughly, and it analyzes the data through an exploratory research approach to propose a zakat model for the digital assets.

This research aims to develop a zakat model for digital assets within the framework of Sharīʿah. Using a qualitative research method, the study thoroughly examines existing literature and uses an exploratory research approach to propose this zakat model. The findings suggest that digital assets hold the potential to be considered for zakat in the contemporary digital age. Previous studies indicate that both commodity-based and currency-based digital assets meet the criteria for zakat imposition. Given zakat’s significant impact on socioeconomic development, it is imperative to carefully manage these assets to maximize their potential benefits. However, variations in interpretations by different jurisdictions and Sharīʿah scholars regarding the understanding and classification of digital assets lead to ongoing scrutiny from legal and religious perspectives. This research aims to contribute to the discourse by proposing a zakat model for digital assets and identifying potential assets eligible for zakat.

This research seems to be the pioneer in providing a zakat model for digital assets, combining different segments of digital assets.

This paper aims to investigate the relationship between voluntary disclosure and the cost of capital as a direct relationship and as an indirect relationship mediated by information asymmetry. It provides evidence from Jordan as a developing economy.

The sample was selected from the companies listed in the first market of the Amman Stock Exchange during the period 2010–2019. Four exclusion criteria were used in selecting the companies for analysis.

The findings show that the cost of capital and information asymmetry are negatively affected by voluntary disclosure, as well as that the cost of capital is positively affected by information asymmetry. In addition, information asymmetry does not mediate the relationship between voluntary disclosure and the cost of capital.

This research looks at the mediating effect of information asymmetry in the relationship between voluntary disclosure and the cost of capital; thus, it provides new explanations about it using empirical evidence from a developing economy. As a necessary consequence, this research has the potential to significantly contribute to the existing body of knowledge and literature in this field.
