I add: Ibn ʿAsākir also transmitted from him (1).
Ibn al-Jawzī says: “He preached in the Qasr Congregational Mosque and would remark, ‘In the art of preaching I am but a beginner.’ He composed a set of sermons that he delivered, embedding within them the Ashʿarī creed; they became widely accepted. However, he slighted the hadith scholars and the Hanbalīs, so he was removed in short order (2).”
I further note: He passed away in middle age. His father (3), Abū ʿAbd Allāh, was a leading authority on Arabic language and grammar. He compiled al-Qānūn, a ten-volume lexicon, produced a Qurʾān commentary, authored a work on the causes of variant readings, studied under Ibn Burhān, transmitted hadith from Ibn Ghaylān, and the men of letters in Isfahan trained under him.
Al-Silafī narrated from him as well.
He died in 493 AH. The sons of Niẓām al-Mulk acquired their refinement at his hand, and he had grown very old by then.

(4) Yaqut notes that Hilla Bani Mazid was a large town between Kufa and Baghdad, formerly known as al-Jamʿiʿayn. The author of al-Rawd al-miʿtar (p. 197) adds that it was a lofty, sizeable city on the eastern bank of the Euphrates, stretching along the river.
