The Global Muslim Travel Index has estimated that the number of Muslim travellers would reach 230 million and contribute US$300 billion to the world economy. In the past few years, many Muslim and non-Muslim destinations and service providers in tourism have launched their plans to attract Muslim travellers and become Muslim friendly destinations. To meet the needs of destinations and tourism and hospitality service providers on how to deal with this emerging market, Muslim tourism and its related issues have captured the attention of academic researchers. However, it is still in an early stage. Accordingly, the present review aims to investigate what has already been conducted and define a direction for future studies. Results of this study show that Muslim tourism is an emerging trend, where most collaborations towards knowledge development are between Muslim countries. Exploring the most frequently studied variables, clustering the studies, and classifying the Muslim friendly destination’s requirements are other discussed issues that can be helpful for destinations and future studies.
