"It has been narrated on the authority of Jabir that the Messenger of Allah said: Who will kill Ka'b b. Ashraf? He has maligned Allah, the Exalted, and His Messenger. Muhammad b. Maslama said: Messenger of Allah, do you wish that I should kill him? He said: Yes. He said: Permit me to talk (to him in the way I deem fit). He said: Talk (as you like)."
