We have explained in various ways in this Quran, for the benefit of mankind, all kinds of examples, but man is most contentious. 54 Nothing prevented people from believing and seeking the forgiveness of their Lord when guidance came to them, unless they are waiting for the fate of the ancients to overtake them, or that the punishment should come upon them face to face. 55 We send not the messengers save as bearers of good news and warners. Those who disbelieve contend with falsehood in order to refute the Truth thereby. And they take Our revelations and that wherewith they are threatened 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 your Lord is the Oft Forgiver, the Merciful; if He seized them for their deeds, He would soon send the punishment upon them; but for them is an appointed time from which they will not find any refuge. 58 And these towns – We destroyed them when they committed injustice, and We had set an appointed time for their destruction. 59
