Unveiling Defects of the Transmitters of Ḥadīth and Relaters of Reports and the Statements of the A’immah Regarding That

Bishr bin al-Hakam narrated to me, he said, I heard Yahyā bin Sa’īd al-Qattān weaken Hakīm bin Jubayr and Abd al-A’lā; and he weakened Yahyā Mūsā bin Dīnār [there is no ‘bin’ between ‘Yahyā’ and ‘Mūsā’]; [Yahyā] said: ‘His Ḥadīth are Rīh or ‘wind’ [i.e., not established and weak]. [Yahyā] weakened Mūsā bin Dihqān and Īsā bin Abī Īsā al-Madanī. [Muslim] said, ‘I heard al-Hasan bin Īsā saying ‘Ibn al-Mubārak said to me: ‘When you go to Jarīr then write down all of his knowledge except the Ḥadīth of 3 [people] - do not write the Ḥadīth of Ubaydah bin Mu’attib, as-Sarī bin Ismā’īl, or Muhammad bin Sālim’.’
