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.

After Muhammad's final battle against his Meccan enemies, he diverted his attention to stopping the Banu Mustaliq's raid on Medina. During this skirmish, Medinan dissidents, begrudging Muhammad's influence, attempted to attack him in the more sensitive areas of his life, including his marriage to Zaynab bint Jahsh, and an incident in which Aisha left her camp to search for her lost necklace, and returned with a Companion of Muhammad.
