Shia–Sunni relations
The succession to Muhammad in 632 led the Muslims to be split into two camps: the Sunnis, who believed that the caliphs of the Islamic community should be chosen by a council, as in Saqifa; and a second group, the Shia, who believed that Muhammad had named his successor to be Ali ibn Abi Talib, his cousin and son-in-law. Today there are differences in religious practice and jurisprudence, traditions, and customs between Shia and Sunni Muslims.
