a great deal [of Hadith]—as stated by al-Dhahabi in the biographical entry for Ahmad in his Mu‘jam, where he named him Ahmad ibn Abi al-Qasim! In the published edition of al-Tabsīr, it is mentioned that he was his sister’s son, but this is a scribal error.
‘Abd al-Mu’min ibn Khalaf al-Dimyati, in his Mu‘jam.
Abu ‘Abdullah ... ibn ‘Abdullah al-Rumi al-Zajjaj (who read the book Al-Hadd under his instruction).
His Scholarly Works:
He has commentaries and compilations (as noted by al-Dhahabi in Al-Tarikh), including:
Kitab Ithbat al-Hadd (The Book of Affirming the Limit), which is the work at hand.
A book on the transmission paths of the Atit (creaking of the Throne) Hadith. In his book Ithbat al-Hadd, following the Atit Hadith, he remarked: “I shall, God willing, present it in a work other than this, with its transmission paths and chains of narration, along with the scholars’ discourse regarding the reliability of its men and the authenticity of its narrators, in a way that allows no means for rejection or refutation except through obstinacy, and no grounds to impugn its authenticity except through sheer stubbornness.” However, the scribe placed a mark of uncertainty (dabbaba) over this passage.
Al-Dashti mentioned similar remarks regarding Ibn al-Zaghuni.
