Sahih Muslim — Hadith #7600

Narrated by Muhammad bin Abd Allah bin Quhzādh: Ali bin Husayn bin Wāqid informed me that Abd Allah bin al-Mubārak said: “I said to Sufyān ath-Thawrī: ‘Indeed, Abbad bin Kathīr, whose situation you know, when he narrated…’” He said: “When I was in a gathering and Abbad was mentioned, I would praise him for his religion but I would say: ‘Do not take any hadith from him.’” Muhammad said: Abd Allah bin Uthmān narrated to us, he said, my father said, Abd Allah bin al-Mubārak said: “I found myself in a gathering of Shu’bah, and he said: ‘Here is Abbad bin Kathīr, so beware of him.’”
