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.
Abbas ibn Ali
Al-Abbas had three sons – Ubaidullah, Fadhl and Muhammad – and two daughters. Ibn Shahrashub, the famous historian, recorded that Muhammad was martyred in Karbala with his father. The mother of Ubaidullah and Fadhl was Lubaba. Genealogists have agreed unanimously that the progeny of Al-Abbas came from his son Ubaidullah. Sheikh al-Futouni, however, added that Hassan ibn Abbas had sons and descendants, too. Ubaidullah ibn Abbas, who died in 155 AH, was a celebrated scholar known for his handsomeness, perfect morality, and fine personality. He had three wives.
