Muhammad bin Abd Allah bin Quhzādh narrated to me, he said I heard Abd Allah bin Uthmān bin Jabalah saying, I said to Abd Allah bin al-Mubārak:
‘Who is this man from whom you transmit the Ḥadīth of Abd Allah bin Amr, ‘The day of Fitr is the day of prizes…’?’ [Abd Allah] said: ‘Sulaymān bin al-Hajjāj. Look at what I placed in your hands [of praise] about him’.
Ibn Quhzādh said I heard Wahb bin Zam’ah mentioning about Sufyān bin Abd il-Mālik, he said, Abd Allah –meaning Ibn al-Mubārak- said: ‘I saw Rawh bin Ghutayf, the companion of blood the amount of a Dirham , and I took a seat in one of his audiences. Then I began to become ashamed for my companions to see me sitting with him while his Ḥadīth are disapproved of.’
