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
Little is known of Muhammad during his later youth, available information is fragmented, making it difficult to separate history from legend. It is known that he became a merchant and "was involved in trade between the Indian Ocean and the Mediterranean Sea." Due to his upright character he acquired the nickname "al-Amin" (Arabic: الامين), meaning "faithful, trustworthy" and "al-Sadiq" meaning "truthful" and was sought out as an impartial arbitrator. His reputation attracted a proposal in 595 from Khadijah, a 40-year-old widow. Muhammad consented to the marriage, which by all accounts was a happy one.
