A universal, comparative history of the study of religions is still far from being written. Indeed, such a history is even hr from being conceived, because its components among the legacies of non-Western scholars have hardly been discovered. One such component, perhaps the most significant one, is the contributions made by Muslim scholars during the Middle Ages to this discipline. What is generally known and what has been documented in this field consists entirely of the contribution of Western scholars of religion. Even these Western scholars belong to the post-Enlightenment era of Western history.
