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.
Fatima and the Daughters of Muhammad
Fatima and the Daughters of Muhammad (French "Fatima et les Filles de Mahomet") is a book written by Henri Lammens (Rome and Paris: "Scripta Pontificii Instituti Biblici", 1912), in which he claims that Muhammad had not intended his succession to go through children of Fatima and she was not Muhammad's favourite daughter. He also claims that Muhammad's household, the Ahl al-Bayt, consisted exclusively of his wives, to the exclusion of his blood relations. Louis Massignon criticized Lammens for 'misinforming' his readers with his 'far too cynical and disparaging study' of Fatima.
