We have explained in various ways in this Quran, for the benefit of mankind, all kinds of examples, but man is most contentious. 54 And nothing prevents men from believing, now when the guidance (the Quran) has come to them, and from asking Forgiveness of their Lord, except that the ways of the ancients be repeated with them (i.e. their destruction decreed by Allah), or the torment be brought to them face to face? 55 But We send [Our] message-bearers only as heralds of glad tidings and as warners - whereas those who are bent on denying the truth contend [against them] with fallacious arguments, so as to render void the truth thereby, and to make My messages and warnings a target of their mockery. 56 And who does greater evil than he who, being reminded of the signs of his Lord, turns away from them and forgets what his hands have forwarded? Surely We have laid veils on their hearts lest they understand it, and in their ears heaviness; and though thou callest them to the guidance, yet they will not be guided ever. 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
