In essence, Islamic law (Maqasid al-Shariah) and the sustainable development goals (SDGs) initiated by the United Nations have the same goal: to achieve the perfection of a sustainable human life. Meanwhile, Islamic finance is regarded as an implementation of Islamic law, as many Islamic finance products and instruments are derived from Islamic law. Prior studies on Islamic law, Islamic finance, and SDGs tend to be scattered, and the role of Islamic finance in SDGs is still questionable. This paper uses a systematic literature review to investigate the intersection of Islamic finance, Islamic law, and SDGs. We selected papers that focused on Islamic finance as an inclusion criterion and excluded papers that only discussed Islamic countries as an exclusion criterion. We retrieved 65 papers and book chapters published from 2008 to 2022 from the Scopus database to analyze which parts of Islamic finance and law can contribute to the SDGs. We use thematic analysis for data synthesis by grouping findings into their relation to Islamic law using Al-Ghazali’s Framework of Maqashid Al-Shariah and SDGs from the UN, and then explaining the research results using a narrative method. Through this study, we found that Islamic finance supports the SDGs with the most significant contribution to humanity. In addition, it is essential to know that the support of the government, regulators, and related institutions is much needed to improve Islamic finance for the achievement of SDGs.

The Covid-19 pandemic has transformed people's activities in many aspects of human life, including how to conduct field surveys as part of research projects. The pandemic could substantially increase research expenses because the execution of surveys is limited by the activity restrictions imposed by the government. Field surveys during the pandemic are no longer flexible because for safety reasons, both the surveyor and the surveyed participant should be negative for Covid-19 by taking PCR tests. This condition could be problematic because research involving household samples is usually characterized by large sample sizes and wide coverage areas. The survey is also usually conducted directly in households to provide better and more accurate results. This article describes an alternative method for obtaining a representative sample of households using an internet-based survey at an affordable cost without ignoring the validity of the survey. This method can be widely implemented in social and economic field studies. • The sampling method proposed for household research is quota sampling, with the strict application of proportions or controlled quotas. • Recruiting local enumerators and selecting respondents based on the criteria is a tool to ease the validation process and quota control of respondents.

This article investigates the effects of market competition and Islamic banks’ fundamental conditions on Islamic banks’ equity (profit and loss sharing [PLS]) financing. We use a monthly data set on nine Indonesian Islamic banks from 2009 to 2014. Our empirical results show that competition significantly increases Islamic banks’ PLS financing activities, suggesting that Islamic banks use this mode of financing to attract more entrepreneurs. This argument is also strengthened by the negative association between bank fundamentals and equity financing. In addition, we also find that the effects of competition on equity financing decrease when Islamic banks are more stable. Our results call on policymakers to monitor the practices in Islamic banks’ equity financing because of the risk embedded in that mechanism and Islamic banks’ tendency to use such instruments in poor fundamental conditions.
