His birth: in the year 491 AH.

He heard (hadith) from his maternal grandfather ʿAlī ibn Aḥmad ibn Tawq, from Abū al-Barakāt ibn Khamīs, and—while in Baghdad—from Nūr al-Hudā al-Zaynabī and a number of others.

His father (1) was one of the leading scholars of his day, known by the honorific al-Murtaḍā. He pursued legal studies in Baghdad, preached, composed excellent poetry, possessed many virtues, and held the judgeship of Mosul. He is the author of the verses:

Nor do I ever turn my resolve away from your door
Without stumbling over the hems of my cloak.” (2)

He died in 511 AH, at a mature but vigorous age.
