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.
Safiye Sultan
Safiye had been Murad's only concubine prior to his accession, and he continued having a monogamous relationship with her for several years into his sultanate. His mother Nurbanu advised him to take other concubines for the good of the dynasty, which by 1581 had only one surviving heir, Murad and Safiye's son Mehmed. In 1583, Nurbanu accused Safiye of using witches and sorcerers to render Murad impotent and prevent him from taking new concubines. This resulted in the imprisonment and torture of Safiye's servants. Murad's sister Esmehan presented him with two beautiful concubines, which he accepted. Cured of his impotence, he went on to father twenty sons and twenty-seven daughters.
