No study has concurrently verified the religious motives and attitudes that affected the customers' continued intentions to use Islamic banks alongwith the importance of other factors and attributes associated with conventional banking services. This study examines factors affecting customers' attitudestoward Islamic banks based on data obtained from interview surveys conducted in Jordan. The findings show that customers' religious motives, theirevaluations of a bank's compliance with Islamic law as an indication of the customers' religious attitudes toward Islamic banks, and the ease of access tocredit had a positive effect on the customers' intentions to continue using Islamic banks. More specifically, the findings suggest that customers whocontinuously transact with Islamic banks more strongly emphasize religious attitudes, rather than credit constraints (such as the degree of access to credit)and religious motives. This study further reveals that religious attitudes, rather than mere religious motives, were the primary criterion for the customers'continued intent to use Islamic banks, especially when considering the strong effect of their religious attitudes toward Islamic banks.
