صحیح مسلم · Hadith 39

Muhammad bin Abd Allah bin Quhzādh, from the people of Marw, narrated to me, he said Alī bin Husayn bin Wāqid informed me, he said Abd Allah bin al-Mubārak said, I said to Sufyān ath-Thawrī: ‘Indeed Abbād bin Kathīr, about whose condition you are aware, when he related [narrations] he introduced a grave matter- do you believe that it should be said to the people ‘Do not take from him?’ Sufyān said: ‘Indeed!’ Abd Allah [bin al-Mubārak] said: ‘So when I was in an assembly and Abbād was mentioned there, I praised him regarding his Dīn and said: ‘Do not take from him.’ Muhammad said, Abd Allah bin Uthmān narrated to us, he said, my father said, Abd Allah bin al-Mubārak said: ‘I ended up in an assembly of Shu’bah, and he said: ‘This is Abbād bin Kathīr so be warned against him.’
