صحيح مسلم #Introduction 41

English Translation Al-Faḍl bin Sahl narrated to me, he said Yazīd bin Hārūn narrated to us, he said Khalīfah bin Mūsā informed me, he said:‘I entered upon Ghālib bin Ubayd Allah so he began dictating to me ‘Mak’hūl narrated to me this’ and ‘Mak’hūl narrated to me that’. So he prepared to answer the call of nature and stood up, then I looked in his notebook and in it was ‘Abān narrated to me, on authority of Anas’ and ‘Abān on authority of so-and-so’. So I abandoned [listening to his Ḥadīth] and stood up [to leave]’.I heard al-Hasan bin Alī al-Hulwānī saying: ‘I saw in one of the books of Affān a Ḥadīth of Hishām Abīl-Miqdām meaning a Ḥadīth of Umar bin Abd il-Azīz. [In it was written] ‘Hishām said: ‘A man said to be Yahyā bin so-and-so narrated to me, on authority of Muhammad bin Ka’b…’ [Al-Hulwānī] said, I said to Affān: ‘They would say Hishām heard it [directly] from Muhammad bin Ka’b’. So [Affān] said: ‘Indeed Hishām was stricken [with accusations of lying] with regards to this Ḥadīth for he would say ‘Yahyā narrated to me on authority of Muhammad’, then he claimed afterwards that he heard it from Muhammad [directly]’.’
