Umm Habib bint Rabia

She is most consistently identified as al-Sahba, with the kunya Umm Habib. Ibn Sa'd and Mus'ab al-Zubayri transmit Umm Habib bint Rabi'a ibn Bujayr of Banu Taghlib; al-Baladhuri preserves the variant bint Habib ibn Bujayr, while Ibn Hajar's entry uses the nisba al-Tha'labiyya. These differences prevent a definitive reconstruction of every element of her paternal genealogy, but her identity as al-Sahba or Umm Habib and her connection with Umar and Ruqayya remain stable across the principal reports.

The strongest early accounts place her among captives connected with Khalid ibn al-Walid's campaigns against groups of Banu Taghlib in the Ayn al-Tamr region. Genealogical sources preserve her as the mother of Umar al-Akbar and Ruqayya through Ali ibn Abi Talib.

Genealogical works identify Umar al-Akbar ibn Ali and Ruqayya bint Ali as her children, and some accounts describe them as twins. Reliable sources do not preserve a detailed independent record of Umm Habib's birth, death, learning, public activity or personal life. Her historical identity consequently survives mainly through the recorded genealogy of Ali's household and her children.
