Umm al-Hasan bint Hasan al-Mujtaba

Umm al-Hasan belonged to the Hasanid branch of the Prophetic family. Al-Mufid lists her among the children of Imam Hasan al-Mujtaba, peace be upon him, and identifies her mother as Umm Bashir, daughter of Abu Mas'ud al-Ansari. Ibn Sa'd's child list likewise connects Umm al-Hasan with Hasan ibn Ali and Umm Bashir. These sources make her parentage the most secure element of her profile.

The sources usually preserve her by the kunya Umm al-Hasan rather than through a detailed personal biography. In Ibn Sa'd's account of the children of Abd Allah ibn al-Zubayr, she is called Nafisa and then explicitly identified as Umm al-Hasan bint al-Hasan ibn Ali. Nafisa may therefore be retained as a reported personal name, while Umm al-Hasan remains the best-attested public identifier.

Her marriage to Abd Allah ibn al-Zubayr is independently recorded in al-Muhabbar, Ansab al-Ashraf and al-Tabaqat al-Kubra. Ibn Sa'd states that she was the mother of a son named Bakr who died young. The exact date of the marriage and detailed domestic chronology are not preserved, so no precise sequence should be invented from the wider political history of her husband.

Al-Baladhuri also preserves a brief report that Umm al-Hasan and her attendants adopted mourning after Abd Allah ibn al-Zubayr was killed. This shows that she survived him, but the sources used here do not establish her later residence, date of death, funeral or burial. Her historical profile is therefore limited to securely documented lineage, marriage, motherhood and a short remembrance of bereavement.
