Muslim

Among the narrators of hadith of this type are Abdullah bin Muharrar, Yahya bin Abi Anisah, Jarrah bin Minhal Abu Atuf, Abbad bin Kathir, Husain bin Abdullah bin Dhamirah, Umar bin Suhban, and other such people who narrate rejected reports; we do not turn to their narrations nor do we have any concern with such narrations.

Because the well-known position and decision of the scholars regarding accepting the narration of a solitary narrator in hadith is that if he generally agrees with the scholars and reliable memorizers, and he has agreed with them in depth, then in such a case, if he (the solitary narrator) mentions an addition that is not found with his other peers, this addition will be accepted (by the hadith scholars).

But if you see someone narrating from a great (hadith scholar) like Imam Zuhri, who has a large number of students who are memorizers (of hadith), are experts in his and others’ narrations, or he narrates from someone like Hisham bin Urwah (Imam of the Tabi‘in), the hadiths of both of whom are well spread among the scholars, all of them share in their narrations, and in most of their hadiths their students agree with each other, and this person narrates from either or both of them multiple hadiths in which none of their students are his partners, then it is not permissible to accept any such hadith from such people. Allah knows best.
