The study of tourism in the Muslim world can be about religious topics such as hajj and pilgrimage, but it actually means and involves much more.

This review article introduces selected aspects of Islam to non-Muslims and reviews the tourism literature to identify themes and areas for further research. In addition to scholarly goals, an understanding of the patterns and requirements of the growing numbers of Muslim travellers is of practical importance for the tourism industry.Significantly, the Muslim world provides opportunities for studying differences in policy and development decisions that can offer new insights and inform tourism by providing alternative perspectives.
