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 Ali
On August 17, 1967, Ali married Belinda Boyd. After the wedding, she, like Ali, converted to Islam. She changed her name to Khalilah Ali, though she was still called Belinda by old friends and family. They had four children: Maryum "May May" (born 1968), twins Jamillah and Rasheda (born 1970; Rasheda married Robert Walsh and has a son Biaggio Ali, born in 1998), and Muhammad Ali Jr. (born 1972). Maryum has a career as an author and rapper.
