Al-Fath al-Mawsili
Abu Naṣr Abu Muḥammad ibn Saʿīd () more commonly known as Al-Fatḥ al-Mawṣilī () (died 835) was an Arab ascetic, weeper ("bakkāʾ") and a "hadith" transmitter. He was born in Kar, Mosul, hence the "nisba" al-Mawsili. Al-Fath lived in the Abbasid capital of Baghdad, and he was a contemporary and a close friend of Bishr al-Ḥafi (died 227 AH/c. 841 AD). Both Al-Fath and Bishr has been claimed as forebears by later Ṣufis.
