Mahmūd bin Ghaylān narrated to us, he said, I said to Abū Dāwud at-Tayālisī: ‘You transmit a great deal on authority of Abbād bin Mansūr - so how is it that you did not hear the Ḥadīth of ‘the lady perfume seller’ from him which an-Naḍr bin Shumayl transmitted to us?’ [Abū Dāwud] said to me: ‘Be quiet, for Abd ar-Rahma bin Mahdī and I met Ziyād bin Maymūn and asked him, saying to him, ‘Are these Ḥadīth you transmit on authority of Anas?’ [Ziyād] said: ‘Have you seen a man sin and then repent- does Allah not turn to him?’ [Abū Dāwud] said: ‘We said, ‘Yes’.’ [Ziyād] said: ‘I did not hear from Anas whether a little or a lot; if the people did not know, then you two would not know that I did not meet Anas’. Abū Dāwud said: ‘So it reached us afterwards that he was transmitting [from Anas] , then Abd ar-Rahman and I went to him and he said: ‘I repented’. Then afterwards he was narrating [again in the same fashion] so we abandoned him ’.

Hasan al-Hulwānī narrated to us, he said, I heard Shabābah say: ‘Abd ul-Quddūs was narrating to us saying,‘Suwayd bin Aqalah said…’ [when it should be ‘bin Ghafalah’] Shabābah said: ‘And I heard Abd ul-Quddūs saying, ‘The Messenger of Allah, peace and blessings of Allah upon him, prohibited taking a Rawḥ by accident’. [Shabābah] said: ‘So it was said to him, ‘What does this mean?’ [Abd ul-Quddūs] said: ‘It means to make an opening in a wall [thus letting] a breeze enter [by accident] ’.’ [He changed the original Ḥadīth, switching ‘Rūḥ’ meaning ‘soul’ to ‘Rawḥ’ or ‘breeze’, and he switched ‘Gharaḍān’ meaning ‘as a target’ to ‘Arḍān’ or ‘accidentally’. All simply by changing a few letters in the words] Muslim said, I heard Ubayd Allah bin Umar al-Qawārīrī saying, I heard Hammād bin Zayd saying to a man after he sat with Mahdī bin Hilāl for days: ‘What is this salty well [i.e. useless or harmful] which has sprung up in your direction?’ He said: ‘Yes, oh Abā Ismā’īl [in agreement] ’.

Al-Hasan al-Hulwānī narrated to us, he said, I heard Affān say, I heard Abū Awānah say: ‘A Ḥadīth did not reach me on authority of al-Hasan except I presented it to Abān bin Abī Ayyāsh , then he read it to me ’.

Suwayd bin Sa’īd narrated to us, Alī bin Mus’hir narrated to us, he said: ‘Hamzah az-Zayyāt and I heard from Abān bin Abī Ayyāsh something like one thousand Ḥadīth’. Alī said: ‘So I met Hamzah then he informed me that he saw the Prophet, peace and blessings of Allah upon him, [in a dream] , and he produced for him what he heard from Abān. However he [the Prophet] didn’t recognize any except a small amount [like] five or six [Ḥadīth] ’.

Abd Allah bin Abd ar-Rahman ad-Dārimī narrated to us, Zakariyyā’ bin Adī informed us, he said, Abū Ishāq al-Fazarī said to me: ‘Write from Baqiyyah what he transmits on authority of those who are well-known, and do not write from him what he transmits on authority of those who are not; do not write from Ismā’īl bin Ayyāsh what he transmits on authority of those who are well-known or otherwise ’.

Ishāq bin Ibrāhīm al-Hanthalī [bin Rāhwayh] narrated to us, he said, I heard one of the companions of Abd Allah [bin al-Mubārak] say, Ibn al-Mubārak said: ‘What an excellent man is Baqiyyah, if it were not for the fact that he would provide a nickname for [those who were better-known by] the birth name, and he would provide the birth name for [those who were better-known by] a nickname. For a long time he would narrated to us on authority of Abī Sa’īd al-Wuhāthī, then when we investigated [we were surprised that] he was Abd ul-Quddūs ’.

Ahmad bin Yūsuf al-Azdī narrated to me, he said, I heard Abd ar-Razzāq saying: ‘I did not see Ibn al-Mubārak express so plainly the charge of ‘lying’ except towards Abd ul-Quddūs; for indeed I heard him saying to him ‘ [You are] a liar’.’

Abd Allah bin Abd ar-Rahman ad-Dārimī narrated to me, he said: ‘I heard Abū Nu’aym and he mentioned al-Mu’allā bin Urfān, so [Abū Nu’aym] said, [al-Mu’allā] said: ‘Abū Wā’il narrated to us, he said ‘Ibn Mas’ūd attacked us on the day of Siffīn’. So Abū Nu’aym said: ‘Do you think he was raised after death? [Ibn Mas’ūd passed away in 32 or 33H, several years before the day in question]

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’.
