Purpose This study aims to analyse the existing literature on the utilisation of financial technology (FinTech) in the Islamic social finance (ISF) sector, focusing on tools, applications and benefits. From this study, it is to provide insights for literature or for practitioners on how FinTech can be used in ISF, such as using blockchain (tools) in waqf (application) that can help to enhance transparency and trust (benefits) with donors. It is important to explore new available tools or applications in ISF markets so that such effort can benefit the industry in promoting its growth. Design/methodology/approach A systematic literature review (SLR) was carried out using Reporting Standards for Systematic Evidence Syntheses (ROSES) which has been based on quality evaluation criteria, beginning with 41,945 entries in Scopus, 25,386 entries in the Web of Science and 1,590 entries in the Google Scholar databases and ending with 35 articles from data abstraction and analysis, all of which focus on tools, applications and benefits of FinTech in ISF sector. Findings This review yielded three primary themes and eleven sub-themes addressing FinTech, namely applications (four sub-themes: crowdfunding, blockchain, banking service and peer-to-peer (P2P), tools (three sub-themes: waqf, zakat and sadaqah), as well as benefits (four sub-themes: transparency, innovation, inclusiveness and efficiency). Research limitations/implications This study emphasises on innovative application of FinTech used in ISF industry which focuses on applications, tools and benefits of FinTech to the industry. However, the findings indicate that there is plenty of room for future investigation. The current work outlines several methodological issues and concerns as well as provides recommendations for future research. Various challenges associated with FinTech applications include inadequate regulations, complex permit application procedures, misuse of FinTech for terrorist financing, the existence of fraudulent FinTech companies and consumer disputes in the FinTech sector concerning ISF. There are few in-depth studies on the possible use of FinTech models in ISF, compared to studies focusing on upcoming challenges. This study also highlights the methodological limitations in previous research efforts, which can be used to improve future studies in this area. To offer a more comprehensive analysis, additional search keywords and engines that have not been included in this study could be used in future investigations with different methodologies. Practical implications For practitioners, the paper has significant managerial consequences. The analysis provides insights into real-life opportunities, limits and solutions for improving performance management by looking at FinTech applications from a larger and more diverse perspective. The practitioners, especially the State Islamic Religious Council, can recognise the benefits of using FinTech technology in ISF (waqf, zakat and sadaqah), namely under their jurisdiction. Originality/value This systematic literature assessment identifies critical knowledge gaps that must be addressed such as the applications of FinTech that are still ambiguous, with certain applications not completely embraced in the ISF industry. This study uses SLR technique to categorise literature, identify gaps in current studies and provide recommendations for the research issue (Paul and Criado, 2020), instead of using the other previous methodology such as content analysis or qualitative review. Hence, FinTech is considered an innovative or new approach in ISF industry.
