Fāṭimah bint Muḥammad al-Taymī (Arabic: فاطمة بنت محمد التيمي) was the third influential wife of the Abbasid caliph al-Mansur.
Al-Mansur's first wife was Arwa, known as Umm Musa, whose lineage went back to the kings of Himyar.
[1] According to their pre-marital agreement, while Arwa was still alive, al-Mansur had no right to take other wives and have concubines in the Abbasid harem.
Al-Mansur tried to annul this agreement several times, but Arwa always managed to convince the judges to not accede to the caliph's attempts.
Fatimah was related to the several members of the Abbasid ruling house of the Caliphate.
