Abstract. Despite the exponential growth in the Muslim population across the world, a large gap still exists between the number of existing customers of Islamic banking and the number of potential customers. Previous and numerous studies in the field of consumer research have demonstrated the associations among religious affiliation, religiosity, consumer life style, and consumer behavior. The current study aims to examine the role of religiosity in the adoption of Islamic banking among Muslim customers. A literature review shows mixed results regarding the role of religiosity in the adoption of Islamic banking.
