Al-Kahf 18:56

Wama nursilu almursaleena illamubashshireena wamunthireena wayujadilu allatheenakafaroo bilbatili liyudhidoo bihi alhaqqawattakhathoo ayatee wama onthiroohuzuwa

And We send not the messengers except as bringers of good tidings and warners. And those who disbelieve dispute by [using] falsehood to [attempt to] invalidate thereby the truth and have taken My verses, and that of which they are warned, in ridicule.

We send the messengers only as bearers of good tidings and warnings, and those who disbelieve raise disputes on the basis of the false (arguments), so that they may nullify the truth with it; and they have taken My signs, and the warnings given to them, as mockery.
