Abu Dawud said: Qutaibah mentioned the name Jaftar b. Rabi'ah in the middle of the text of the tradition for the second time (i.e., Qutaibah, being doubtful about the narrator Jafar b. Rabi'ah, mentioned his name twice: once in the chain and again while reporting the text). Ali b. "Ayyash and yunus b. Muhammad reported it on the authority of al-Laith. They mentioned the name Jafar b. Rabi'ah.
