مسند أحمد

It was narrated that Rib`i said: I heard `Ali (رضي الله عنه) say: The Messenger of Allah (ﷺ) said: “Do not tell lies about me, because whoever tells a lie about me will enter Hell.” Hajjaj said: I said to Shu`bah: Did he meet `Ali? He said. Yes; he narrated it to me from ‘Ali. And he did not say he heard it. It was narrated from Rib’i bin Hirash that he heard `Ali (رضي الله عنه) deliver a khutbah; he said: The Messenger of Allah (ﷺ) said... and he narrated a similar report.
