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
Before he left for Medina, it was suggested by Khawlah bint Hakim that he marry Sawda bint Zamʿa, who had suffered many hardships after she became a Muslim. Prior to that, Sawda was married to a paternal cousin of hers named As-Sakran bin ‘Amr, and had five or six sons from her previous marriage. There are disagreements in Muslim tradition whether Muhammad first married Sawda or Aisha. In one account, he married Sawda in Shawwal, when Sawda was about 55 years old, in the tenth year of Prophethood, after the death of Khadija. At about the same period, Aisha was betrothed to him. As Sawda got older, and some time after Muhammad's marriage to Umm Salama, some sources claim that Muhammad wished to divorce Sawda. Still other traditions maintain that Muhammad did not intend to divorce her, but only Sawda feared or thought that he would. As a compromise, or because of her old age, Sawda offered to give her turn of Muhammad's conjugal visits to Aisha, stating that she "was old, and cared not for men; her only desire was to rise on the Day of Judgment as one of his wives". While some Muslim historians cite this story as a reason of revelation for , others like Rashid Rida dispute this whole account as "poorly supported", or mursal.
