After spending years amongst Jews, Christians, and pagans, Muhammad underwent a transformation: according to Muslim teachings, the archangel Gabriel appeared to Muhammad and commanded him to receive the revelation of the one and only Allah (the Arabic word for God). At forty-one years old, Muhammad declared himself the final messenger in a history of religious revelation that had begun with Abraham and continued through Moses and Jesus.
