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.
Subh-i-Azal
According to Browne, Mirza Yahya had several wives, and at least nine sons and five daughters. His sons included: Nurullah, Hadi, Ahmad, Abdul Ali, Rizwan Ali, and four others. Rizvan Ali reports that he had eleven or twelve wives. Later research reports that he had up to seventeen wives including four in Iran and at least five in Baghdad, although it is not clear how many, if any, were simultaneous. According to Azali sources, Subh-i-Azal had five wives in total.
