He learned from Ahmad ibn Yusuf as-Sulami, ʿAli ibn al-Hasan al-Hilali, Hamid ibn Mahmud, and a number of others.
During his journeys he also took transmission from Yahya ibn Jaʿfar, ʿAbbas ad-Duri, and Muhammad ibn Ishaq as-Saghani, and his repertory of reports was vast.
Narrators from him include: Abu Bakr ibn Ishaq as-Sibghi, Abu ʿAli al-Hafiz, ʿAbd Allah ibn Saʿd, Ibn Manda, Ibn Mahmish, Muhammad ibn Ibrahim al-Jurjani, and others besides.

Abu ʿAbd Allah al-Hakim said, “I frequented him for more than a year, yet did not obtain so much as a single letter of the material I had heard from him. Still, I did hear a great deal from him. (1)”

I also heard Abu an-Nadr the jurist say, “Whenever the imam Ibn Khuzaymah was uncertain about a point of language, he would refer to no one but Abu Tahir al-Muhammadabadi. (2)”

I say: He died in 336 AH, having passed the age of ninety.
He was among the leading trustworthy authorities, deeply versed in the meanings of the Revelation and in Arabic letters.
His narrations appear in the Thaqafiyyat (3) and elsewhere.
