Fāṭimah bint Ḥuzam al-Kulābīyya (died 64 A.H. (683/684) or 69 A.H. (688/689)), commonly known as Umm ul-Banin ("mother of several sons"), was from the tribe of Banu Kilab a branch of Qais Ailan tribes.
She married Ali ibn Abi Talib after the death of his first wife Fatimah, daughter of the Islamic prophet, Muhammad. Umm ul-Banin and Ali had four sons, of whom the eldest was Abbas ibn Ali, the commander of Husayn ibn Ali's forces at the Battle of Karbala. Shimr ibn Dhi 'l-Jawshan, who later killed Husayn ibn Ali at the battle, was from the same tribe as Umm ul-Banin, and he offered safe-conduct to her and her sons before the battle commenced; however, they rejected it since the offer did not include Husayn. All of Umm ul-Banin's sons were killed at Karbala.
It is believed that Umm ul-Banin died in 69 A.H. (688/689) or 13 Jumada al-Thani 64 A.H. (6 February 684), and was buried in the Jannatul Baqi, a cemetery in Medina. The descendants are called as Sadaat-e-Alvi or Awans
