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.
Muhammad's wives
One of the captives from the skirmish with the Banu Mustaliq was Juwayriyya bint al-Harith, who was the daughter of the tribe's chieftain. Her husband, Mustafa bin Safwan, had been killed in the battle. She initially fell among the booty of Muhammad's companion Thabit b. Qays b. Al-Shammas. Upon being enslaved, Juwayriyya went to Muhammad requesting that she - as the daughter of the lord of the Mustaliq - be released, however the Prophet refused. Meanwhile, her father approached Muhammad with ransom to secure her release, but Muhammed still refused to release her. Muhammad then offered to marry her, and she accepted. When it became known that tribes persons of Mustaliq were kinsmen of the prophet of Islam through marriage, the Muslims began releasing their captives. Thus, Muhammad's marriage resulted in the freedom of nearly one hundred families whom he had recently enslaved.
