His son, Abū al-Walīd, lived on until a little after 440 AH, and he was the last person to narrate directly from his father.

Ibn Khallikān said: “Abū Bakr was peerless in his age in the science of grammar and in safeguarding the Arabic language. Of all the people of his time he was the most knowledgeable about parsing (iʿrāb), meanings, and rare usages, in addition to his mastery of biography and historical reports. In al-Andalus no one of his craft equalled him in his day.”

Among the works that attest to his learning are: The Classes of Grammarians and Lexicographers; a refutation of Ibn Masarra; several other valuable treatises; and he also composed exquisite poetry.(1)

306 – Ibn al-Muẓaffar, Muḥammad ibn al-Muẓaffar ibn Mūsā al-Baghdādī *
The shaykh, ḥāfiẓ, precisionist, and leading traditionist of Iraq: Abū al-Ḥusayn Muḥammad ibn al-Muẓaffar ibn Mūsā ibn ʿĪsā ibn Muḥammad al-Baghdādī.

He said, “My father was from Sāmarrāʾ, and I myself was born in Baghdad at the beginning of the year 286 AH; my first audition of ḥadith was in 300 AH.”

It was said that he was a descendant of Salama ibn al-Akwaʿ—may Allah be pleased with him. When asked about this, he replied, “I do not know whether that is authentic.”

He heard ḥadith from: Ḥāmid ibn Shuʿayb al-Balkhī; Abū Bakr ibn al-Bāghandī; Abū al-Qāsim al-Baghawī; al-Haytham ibn Khalaf al-Dūrī; Qāsim ibn Zakariyyā al-Muṭarraz; Aḥmad ibn al-Ḥasan al-Ṣūfī; Muḥammad ibn Jarīr al-Ṭabarī; and ʿAbd Allāh ibn Ṣāliḥ.
