Those who deny use fallacious arguments to nullify the truth, treating My revelations and My warnings as a jest. 56 And who could be more wicked than he to whom his Sustainer's messages are conveyed and who thereupon turns away from them, forgetting all [the evil] that his hands may have wrought? Behold, over their hearts have We laid veils which prevent them from grasping the truth, and into their ears, deafness; and though thou call them onto the right path, they will never allow themselves to be guided. 57 And thy Lord is the Forgiver, Owner of mercy. Were He to call them to account for that which they have earned; He would have hastened for them torment; but for them is a tryst beside which they cannot find a place to betake themselves to. 58 And (all) those townships! We destroyed them when they did wrong, and We appointed a fixed time for their destruction. 59
