Muhammad's wives
Muhammad was monogamous for 25 years. After his first wife Khadija bint Khuwaylid died, he proceeded to marry the wives listed below, and most of them were widows. Muhammad's life is traditionally delineated as two epochs: pre-hijra (emigration) in Mecca, a city in western Arabia, from the year 570 to 622, and post-hijra in Medina, from 622 until his death in 632. All but two of his marriages were contracted after the Hijra (migration to Medina). Of Muhammad's thirteen wives, at least two, Rayhana bint Zayd and Maria al-Qibtiyya, were referred to simply as concubines; however, there is debate among Muslims as to whether these two officially became his wives. Of his thirteen wives, only two bore him children, a fact which has been described as "curious" by Cornell University Professor of Near Eastern Studies David S. Powers.
Antisemitism in Islam
During Muhammad's life, Jews lived in the Arabian Peninsula, especially in and around Medina. Muhammad is known to have had a Jewish wife, Safiyya, who subsequently converted to Islam. The story of Safiyya ties into the Battle of Khaybar where, according to the Hadiths, Muhammad and the Muslim army conquered the city and the women and children were subsequently distributed as prisoners of war. Safiyya, who was the wife of Kenana ibn al-Rabi, was selected by Muhammad as his bride.
