Amr bin Alī and Hasan al-Hulwānī narrated to me, both of them on authority of Affān bin Muslim, he said
‘We were near Ismā’īl bin Ulayyah, and a man narrated on authority of another man, so I said: ‘Indeed this is not reliable (Thabt)’. So the man said: ‘Are you backbiting him?’ Ismā’īl said: ‘He is not backbiting him; rather he is judging him unreliable’. Abū Ja’far ad-Dārimī narrated to us, Bishr bin Umar narrated to us, he said: ‘I asked Mālik bin Anas about Muhammad bin Abd ar-Rahman who transmits on authority of Sa’īd bin al-Musayyib, so he said: ‘He is not trustworthy ‘. I asked him about Sālih, a freed slave of at-Taw’amah, then he said: ‘He is not trustworthy’. I asked him about Abūl-Huwayrith , and he said: ‘He is not trustworthy’. I asked him about Shu’bah on whose authority Ibn Abī Dhi’b transmitted, and he said: ‘He is not trustworthy’. I asked him about Harām bin Uthmān , and he said ‘He is not trustworthy’. I asked Mālik about these five and he said: ‘They are not trustworthy in terms of their Ḥadīth’. I asked him about another man whose name I forget just now, and he said: ‘Did you see him in my book?’ I said: ‘No’. [Then] he said: ‘If he was trustworthy you would see him in my book’. Al-Faḍl bin Sahl narrated to me, he said: ‘Yahyā bin Ma’īn narrated to me, Hajjāj narrated to us, Ibn Abī Dhi’b narrated to us on authority of Shurahbīl bin Sa’d , and he was imputed [with lying regarding Ḥadīth near the end of his life]’. Muhammad bin Abd Allah bin Quhzādh narrated to me, he said, I heard Abū Ishāq at-Tālqānī saying, I heard Ibn al-Mubārak saying: ‘If I had to choose between entering Paradise and meeting Abd Allah bin Muharrar, I would have chosen to meet him, then enter Paradise. Then when I saw him, dung was more preferred to me than him’. Al-Faḍl bin Sahl narrated to me, Walīd bin Sālih narrated to us, he said, Ubayd Allah bin Amr said, Zayd- meaning Ibn Abī Unaysah – said: ‘Do not take [Ḥadīth] from my brother ’. Ahmad bin Ibrāhīm ad-Dawraqī narrated to me, he said, Abd us-Salām al-Wābisī narrated to me, he said, Abd Allah bin Ja’far ar-Raqqī narrated to me, on authority of Ubayd Allah bin Amr, he said: ‘Yahyā bin Abī Unaysah was a liar’. Ahmad bin Ibrāhīm narrated to me, he said, Sulaymān bin Harb narrated to me, on authority of Hammād bin Zayd, he said, Farqad was mentioned near Ayyūb, so he said: ‘Indeed Farqad is not a companion of Ḥadīth’. Abd ur-Rahman bin Bishr al-Abdī narrated to me, he said, I heard Muhammad bin Abd Allah bin Ubayd bin Umayr al-Laythī was mentioned near Yahyā bin Sa’īd al-Qattān, so he weakened him severely. Then it was said to Yahyā: ‘More weak than Ya’qūb bin Atā ’?’ He said: ‘Yes’. Then he said: ‘I did not see anyone transmitting on authority of Muhammad bin Abd Allah bin Ubayd bin Umayr’.
