Abu Al-Qasim Al-Fadl bin Mohammed bin Ali bin Al-Fadl Al-Qasabani (died 444 AH), was a well known Arab philologist and grammarian of the Abbasid Caliphate.
He was born in Basra, in the Bani Haram neighborhood, where he spent his entire life.[1] He was blind,[2] and many students of knowledge studied under him, the most famous of whom were: Al-Hariri, Al-Khatib Al-Tabrizi,[3] and the judge of Basra, Abu Al-Faraj Al-Basri.[4]
