Polytheists and the irreligious were anathematized in classical Islam, but it assigned People of the Book, mainly Christians and Jews, to an intermediate protected category, the dhimma. Much writing on this institution takes sides, arguing that it was a mechanism either for interreligious harmony or for persecution of minorities. Anver Emon, in his weighty and original Religious Pluralism and Islamic Law, rejects both opposing views, as well as the concept of tolerance as a useful analytical tool.... [W]hat gives this study a surprising topicality is the comparison that Emon draws with the arguments deployed by Euro-American courts today when rights of religious minorities conflict with the imperative of social cohesion.
