Muhammad (A.D. 570-632) is regarded by Muslims as the last prophet of God. He was an Arab religious, political and military leader who founded Islam and the Muslim community (Arabic: أمة Ummah). His life is traditionally defined into two epochs: pre-hijra (emigration) in Mecca, a city in northern Arabia, from the year 570 to 622, and post-hijra in Medina, from 622 until his death in 632. All but two of his marriages were contracted after the Hijra (migration to Medina).
