Muhammad married at least 15 different women, and he consummated marriages with at least 13 different women. Muhammad's favorite wife, however, was Aisha, the daughter of his best friend, Abu Bakr. Aisha was six years old when Muhammad married her, and she was nine years old when the marriage was consummated. When Muhammad died, Aisha was 18 years old. Since the Qur'an declares that no one can marry Muhammad's wives after him (33:53), Aisha spent the next 46 years as a widow.
