Narrated Nuaym ibn Masud: I heard the Messenger of Allah صلی اللہ علیہ وسلم say when he read the letter of Musaylimah: What do you believe yourselves? They said: We believe as he believes. He said: I swear by Allah that were it not that messengers are not killed, I would cut off your heads.

Narrated Abdullah ibn Masud: Harithah ibn Mudarrib said that he came to Abdullah ibn Masud and said (to him): There is no enmity between me and any of the Arabs. I passed a mosque of Banu Hanifah. They (the people) believed in Musaylimah. Abdullah (ibn Masud) sent for them. They were brought, and he asked them to repent, except Ibn an-Nawwahah. He said to him: I heard the Messenger of Allah صلی اللہ علیہ وسلم say: Were it not that you were not a messenger, I would behead you. But today you are not a messenger. He then ordered Qarazah ibn Kab (to kill him). He beheaded him in the market. Anyone who wants to see Ibn an-Nawwahah slain in the market (he may see him).
