Zainab was one of the three fostered daughters of the Prophet Muhammad (SAWA) and Khadeejah (AS). Many scholars say that the only biological daughter of the Prophet was Fatima (AS). Zainab had a daughter called Umamah bunt Abi Al-A'aas or bint Al-A'aas. Umamah was married to Imam Ali (AS) after the martyrdom of Lady Fatima (AS) and according to Lady Fatima's will. It is mentioned that Umamah has a son called Muhammad Al-Awsat son if Imam Ali (AS) who was martyred in Karbala.
