She was an early convert to Islam, and her son ʿAbdullāh used to say, “My mother and I were counted among the vulnerable—women and children.” Al-Bukhārī narrated this (1). This indicates that the two of them accepted Islam before al-ʿAbbās but were unable to perform the hijra.
Umm al-Faḍl was one of the eminent women; after the Conquest al-ʿAbbās moved with her to Medina.
She transmitted hadiths. Among those who reported from her were her two sons, ʿAbdullāh and Tammām, as well as Anas ibn Mālik, ʿAbdullāh ibn al-Ḥārith, and others. Her narrations appear in all six canonical collections.
I believe she died during the caliphate of ʿUthmān.
In the Musnad of Baqiyy ibn Makhlad she has thirty hadiths, counting repetitions. Al-Bukhārī and Muslim share one hadith from her; another is found only in al-Bukhārī, and a third only in Muslim (2).
It has been said that, after Khadījah, no woman embraced Islam before her.
