Among those who narrated from him were Yaḥyā ibn al-Munajjim, Aḥmad ibn ʿAmmār, Jaʿfar ibn Qudāmah, Yaʿqūb ibn Nuʿaym Qarqārah, and ʿAbd Allāh ibn Abī Saʿd al-Warrāq.
He was an eloquent scribe and a gifted poet. In his later years he became mentally unsettled, having drunk baladhur as a memory aid. He composed panegyrics for the caliph al-Maʾmūn and others. Eventually he was confined to a bīmāristān (public hospital), where he died.
Some said his kunya was Abū al-Ḥasan; others said it was Abū Jaʿfar. He passed away sometime after 270 AH. His grandfather Jābir had been secretary to al-Khaṣīb (1), the governor of Egypt.
