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.
Children of Muhammad
There is much controversy between Sunni and Shia regarding how many daughters Muhammad sired. While most Sunnis accept that he had four daughters, most Shia accept Fatimah as his only biological daughter and that 3 women were already living in the house of Khadijah before her marriage with Muhammad.
