The growing popularity of Islamic banking is occurring swiftly across many countries worldwide. The goal of this study is to assess customer learning and choosing of Islamic banking system in Bangladesh. This study investigates the extent of customer engagement regarding the products provided by Islamic banks in order to evaluate their popularity. This study is correlational in nature. This study is based on both primary and secondary data. We obtained primary data from customers of several Islamic bank branches using purposive sampling, a non-probability sampling approach. We distributed formal, structured questionnaires to the clients of these branches, taking into account demographic factors such as gender differences, marital status, and religion in Bangladesh. We extracted the secondary data from various theoretical reviews, which included papers, academic journals, and books. We examined the data using SPSS to test a number of distinct hypotheses. The chi-square test serves as the data analysis tool in these studies. The analysis revealed that choosing Islamic banking services is not significantly influenced by general education but rather by Islamic education and knowledge about Islamic banking. The produced findings can inform policy decisions for academicians, researchers, and practitioners.
