[Hasan] Tabarani narrated it in his Kabir, 7/224, no. 6935, from the hadith of Quraysh bin Anas. This is noted in Tahdhib, which indicates that the hearing of Muhammad bin Bashshar and Ibn Madini from Quraysh bin Anas is sahih. Hasan's narration from Samura is a written document, so Hasan's tadlis does not harm it, and narration from a book is sahih as long as no criticism of it has been established.
