And surely We have explained matters to people in the Qur'an in diverse ways, using all manner of parables. But man is exceedingly contentious. 54 There is nothing to prevent men from believing when the guidance has come to them, and asking for their Lord's forgiveness, unless they want the example of earlier people visited upon them, or the punishment to appear right before their eyes. 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 doth more wrong than one who is reminded of the Signs of his Lord, but turns away from them, forgetting the (deeds) which his hands have sent forth? Verily We have set veils over their hearts lest they should understand this, and over their ears, deafness, if thou callest them to guidance, even then will they never accept guidance. 57 Your Lord is the Forgiving One, the possessor of mercy. If He had to take them to task for the wrongs they have done, He would have hastened their punishment. They have an appointed time beyond which there will be no escape for them. 58 And those cities, We destroyed them when they did evil, and appointed for their destruction a tryst. 59
