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
According to Muslim tradition, Muhammad's wife Khadija was the first to believe he was a prophet. She was followed by Muhammad's ten-year-old cousin Ali ibn Abi Talib, close friend Abu Bakr, and adopted son Zaid. Around 613, Muhammad began to preach to the public (Quran ). Most Meccans ignored and mocked him, though a few became his followers. There were three main groups of early converts to Islam: younger brothers and sons of great merchants; people who had fallen out of the first rank in their tribe or failed to attain it; and the weak, mostly unprotected foreigners.
