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.
Fatimah
Fatimah bint Muhammad (; ""; born 615 AD, 5 BH – died 28 August 632 ) was the youngest daughter and, according to Shia Muslims, the only child of the Islamic prophet Muhammad and Khadijah who lived to adulthood, and therefore part of Muhammad's household. Her husband was Ali, the last of the Rightly Guided Caliphs, and her children include Hasan and Husayn, the second and third Shia Imams, respectively. She is the object of love and respect of Muslims, as she was the child closest to her father and supported him in his difficulties, was the supporter and loving caretaker of her own husband and children, and was the only child of Muhammad to have male children live beyond childhood, whose descendants are spread throughout the Islamic world and are known as Sayyids.
