Due to the increasing use of e-wallets, it is crucial to evaluate their compliance with Shariah to meet the needs of Muslim customers in line with Islamic principles. This chapter seeks to offer understanding of maqasid al-Shariah in the context of e-wallet usage and financial well-being. In connection with this, the development of financial technology will expand the capabilities and services of e-wallets beyond being just a basic payment tool. This expansion includes multiple funding sources, such as credit cards, buy now, pay later (BNPL), and short-term loans. These multi-sourcing fundings may trigger expenditure, aid, or impede financial well-being. Therefore, a user's spending behaviour can affect the e-wallet usage and their financial well-being. Understanding the results of this research would partly contribute to the general knowledge of Islamic finance and fintech, with the intention of developing Shariah-compliant digital financial solutions suited to the needs of Muslims all over the world.
