He excelled in maʿrifat al-rijāl (the evaluation of narrators), collected and authored works, lived a long life, and his reputation travelled far. Many of the ḥuffāẓ transmitted from him, attesting to his integrity and precision. His fame was unmistakable, though his powers of memorization did not reach the level of al-Dāraqutnī.
Those who narrated from him include: Abū Ḥafṣ ibn Shāhīn, al-Dāraqutnī, al-Barqānī, Ibn Abī al-Fawāris, Abū ʿAbd al-Raḥmān al-Sulamī, Abū Saʿd al-Mālinī, Abū al-Faḍl Muḥammad ibn Aḥmad al-Jārūdī, Abū Nuʿaym, Abū Muḥammad al-Khallāl, Abū al-Qāsim al-Tanūkhī, Abū al-Qāsim (1) al-Jawharī, ʿAbd al-Wahhāb ibn Barhān, the judge Muḥammad ibn ʿUmar al-Dāwūdī, and many others besides them.
Al-Khaṭīb said: “Ibn al-Muẓaffar was intelligent, a ḥāfiẓ, truthful, and exceedingly prolific (2).”
Abū Dharr al-Harawī relates: “I heard Ibn Abī al-Fawāris say:
‘I asked Ibn al-Muẓaffar about a hadith reported by al-Bāghandī, from Ibn Zayd al-Munādī, from ʿAmr ibn ʿĀṣim, from Shuʿbah. He replied, “I do not have it.” I said, “Perhaps it is with you.” He answered, “Had it been with me, I would have memorised it. I possess from al-Bāghandī one hundred thousand hadiths, yet this is not among them.”’
