<P> In 610 CE , Muhammad began receiving what Muslims consider to be divine revelations . Muhammad 's message won over a handful of followers and was met with increasing opposition from notables of Mecca . In 618 , after he lost protection with the death of his influential uncle Abu Talib , Muhammad migrated to the city of Yathrib ( Medina ) . With Muhammad 's death in 632 , disagreement broke out over who would succeed him as leader of the Muslim community which was eventually resurrected leading to the First Fitna . The dispute would intensify greatly after the Battle of Karbala , in which Muhammad 's grandson Hussein ibn Ali was killed by the ruling Umayyad Caliph Yazid I , and the outcry for revenge divided the early Islamic community . </P>
