In this text, the issue of banking in Sepahre Andishe Islamic Bank has been examined. Islamic banking is a type of banking activity that aligns with Islamic principles, particularly regulations aimed at combating usury and exploitation, and is defined within the framework of Islamic economics. The main research question has been to explore the role of Islamic banking in economic development. The research findings indicate that firstly, there is an inseparable relationship between the bank and development. Secondly, the bank, by providing intermediary services, creates a platform for economic growth and development in uncertain conditions, encourages investors to invest, and facilitates the conditions for development. On the other hand, by using Islamic tools in Islamic banking, the groundwork for non-usurious banking activities is rapidly provided. This is because the use of Islamic financial tools, considering the activities of Islamic banking in Islamic countries, will lead banking towards legitimate Sharia profits, ultimately resulting in the complete elimination of usury from banking. This research employs a descriptive analytical method, and the data has been collected through library research.
