Muhammad
Muhammad's life is traditionally defined into two periods: pre-hijra (emigration) in Mecca (from 570 to 622), and post-hijra in Medina (from 622 until 632). Muhammad is said to have had thirteen wives in total (although two have ambiguous accounts, Rayhana bint Zayd and Maria al-Qibtiyya, as wife or concubine.) Eleven of the thirteen marriages occurred after the migration to Medina.
Muhammad's wives
Some of Muhammad's widows were active politically in the Islamic state after Muhammad's death. Safiyya, for example, aided the Caliph Uthman during his siege. During the first fitna, some wives also took sides. Umm Salama, for example, sided with Ali, and sent her son Umar for help. The last of Muhammad's wives, Umm Salama lived to hear about the tragedy of Karbala in 680, dying the same year. The grave of the wives of Muhammed is located at al-Baqīʿ Cemetery, Medina.
