Abu-Muslim Al-Asfahani
He is Muhammad Ibn Bahr Al-Asfahani, born 254 H. and died 322 H. He was a capable writer and speaker, and an isolationist (معتزلي) knowledgeable in interpretation and grammar, and he also wrote poetry. He worked for the Abbasi Khalif Almuqtader-Billah, and wrote for him. He was respected by people in power as well as knowledgeable people at the time.
In
his book, Nada comes to the defense of Al-Asfahany on page 25, joining a number of 20th century scholars in defending him. He says that some have accused Al-Asfahany of denying that Islam abrogated previous revelations, when he only denied abrogation within Islam. Nada says that the goal of these accusations was to undermine Al-Asfahany, and he quotes another scholar (Abu-Alnoor Zuhair) who states that Al-Asfahany is with the majority in that abrogation has indeed occurred, but it has occurred between revelations, not within the same revelation.
