What! is it a wonder to the people that We revealed to a man from among themselves, saying: Warn the people and give good news to those who believe that theirs is a footing of firmness with their Lord. The unbelievers say: This is most surely a manifest enchanter.

And We do not send messengers but as givers of good news and warning, and those who disbelieve make a false contention that they may render null thereby the truth, and they take My communications and that with which they are warned for a mockery.
