al-Muʾammal al-Kafurtābī.

Abū al-Walīd al-Darbandī said, “ʿAbd al-Raḥmān b. ʿUthmān narrated to us in Damascus, and he surpassed a thousand men like him in the soundness of his isnād, the precision of his transmission, and his ascetic life, despite his seniority (1).”

Rashaʾ b. Naẓīf remarked, “I have met many eminent scholars, yet I have never seen anyone comparable to Abū Muḥammad b. Abī Naṣr; he was a joy to behold (2).”

ʿAbd al-ʿAzīz al-Kattānī said, “Our shaykh Ibn Abī Naṣr died in Jumādā al-Ākhirah of the year 420 AH. I have never witnessed a funeral greater than his. In front of the bier stood a group of hadith scholars proclaiming the tahlīl and the takbīr, openly manifesting the Sunnah, and the entire populace of the city attended—even Jews and Christians. I have never met a shaykh his equal in renunciation, scrupulousness, devotion, and stature (3).”

He added, “He was trustworthy, reliable, upright, and accepted.”

He was nicknamed “al-ʿAfīf” (the Chaste).

His autograph manuscripts were of fine quality, penned by Ibn Fuṭays (4) and al-Ḥalabī (5). Abū al-ʿAbbās Ibn al-Simsār compiled for him the various chains of transmission for the hadith, “What an excellent condiment vinegar is” (6).
