He was counted among the foremost pupils of the judge Abū Bakr al-Abharī and is usually mentioned together with Abū al-Qāsim al-Jallāb.
Abū Isḥāq al-Shīrāzī said, “He has an extensive book on disputed legal questions; I do not know of any work on points of disagreement better than it.” (1)
Qāḍī ʿIyāḍ (2) remarked, “He was a scholar of uṣūl and a skilled dialectician, and he held the judgeship of Baghdad.”
Abū Dharr said, “Of all the Mālikīs I met, he was the most learned; he was reliable but narrated only a few ḥadith.” (3)
Ibn Abī al-Fawāris stated, “He died on the eighth of Dhū al-Qaʿda in the year 397 AH.” Others say he died in 398, but the first report is sounder.
