—counted that day among the people of distinction, and ʿAbd al-Raḥmān ibn Mahdī would say, “What does Abu Kamil have to say about a report from the narrations of Ibrāhīm ibn Saʿd?” (1)
Ahmad said, “I heard Abu Kamil some forty years ago. He possessed dignity and gravitas, and he was one of the hadith scholars. He used to remark, ‘The most reliable narrator for Ibrāhīm is Manṣūr.’
Abu Kamil also said, ‘No one who came to us from greater Syria had sounder hadith than al-Layth, whereas Abu Maʿshar could not keep the isnād (chain of transmission) straight.’ (2)
ʿAbd Allah ibn Ahmad related: “I heard Ibn Maʿīn mention Abu Kamil and say, ‘I used to take knowledge of this discipline from him. He was a Baghdadi from the abnāʾ (offspring of the Persian troops settled in Iraq) (3), and he was a righteous man—rarely have I seen anyone like him.’ (4)”
Al-Mufaḍḍal al-Ghalābī narrated from Ibn Maʿīn that he said, “Abu Kamil was reliable, a man devoted to hadith.” (5)(6)
Abu Yaʿlā said, “I heard Abu Khaythamah state, ‘In our estimation Abu Kamil is no less than Wakīʿ is for the Kufans, or ʿAbd al-Raḥmān is for the Basrans.’ (7)"
