It is said that his name was ʿUbayd Allah ibn al-Ḥusayn ibn al-Ḥasan. Qāḍī ʿIyāḍ records it as Muḥammad ibn al-Ḥusayn, adding, “Others say his name was al-Ḥusayn ibn al-Ḥasan.” Shaykh Abū Isḥāq, in Tabaqāt al-Fuqahāʾ, calls him ʿAbd al-Raḥmān ibn ʿUbayd Allah.
He studied law with the judge Abū Bakr al-Abharī and produced a large compendium on disputed issues. After al-Abharī he was the most knowledgeable Mālikī of his time, and Baghdad left no equal to him in the school. He died in middle age at the end of 378 AH, returning from the Hajj.
