Muhammad Muhammad (Arabic: محمد‎ ‎ ; ] ; c. 570 CE – 8 June 632 CE) is the prophet and founder of Islam. According to Islamic doctrine, he was God's Messenger, sent to confirm the essential teachings of monotheism preached previously by Adam, Abraham, Moses, Jesus, and other prophets. He is viewed as the final prophet of God in all the main branches of Islam, though some modern denominations diverge from this belief. Muhammad united Arabia into a single Muslim polity and ensured that his teachings, practices, and the Quran formed the basis of Islamic religious belief.
