(Those are they) who said: Surely Allah has enjoined us that we should not believe in any messenger until he brings us an offering which the fire consumes. Say: Indeed, there came to you messengers before me with clear arguments and with that which you demand; why then did you kill them if you are truthful?

So naught was the answer of his people except that they said: Slay him or burn him; then Allah delivered him from the fire; most surely there are signs in this for a people who believe.
