Ali ibn Abi Talib (598-661) was the cousin and son-in-law of the Islamic prophet Muhammad, Fatima`s husband and ruled over the Islamic Caliphate from 656 to 661, and was the first male convert to Islam. Sunni Muslims consider Ali the fourth and final of the Rashidun, while Shi'a Muslims regard Ali as the first Imam and consider him and his descendants the rightful successors to Muhammad, all of which are members of the Ahl al-Bayt, the household of Muhammad. This disagreement split the Ummah into the Sunni and Shi'a branches.
