Muslim leaders extended religious tolerance to Jews and Christians because Islam recognizes them as "People of the Book" who worship the same God. This commonality fostered a spirit of coexistence in Islamic societies. (option C)
Muslim leaders granted religious tolerance to Jews and Christians due to shared recognition as "People of the Book" following the same God. This principle, rooted in Islamic teachings, facilitated a climate of coexistence. Unlike alternative options like trade benefits or empire strength, the motivation was grounded in religious understanding and unity.
Muslims, acknowledging the common Abrahamic heritage, aimed for harmony among diverse faiths. This approach promoted peaceful cohabitation, fostering an environment where religious diversity was acknowledged and respected. Such religious tolerance contributed to the cultural richness and intellectual flourishing of Islamic civilizations, exemplifying the inclusive ethos encouraged by Islamic teachings.
So option C is correct.
