THUS, INDEED, have We given in this Qur'an many facets to every kind of lesson [designed] for [the benefit of] mankind. However, man is, above all else, always given to contention: 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 And We send not the Envoys, but good tidings to bear, and warning. Yet do the unbelievers dispute with falsehood, that they may rebut thereby the truth. They have taken My signs, and what they are warned of, in mockery. 56 Who is greater in evil than he who, when reminded of the verses of his Lord, turns away from them and forgets what his hands have sent before him? We have placed veils over their hearts lest they should understand it, and there is heaviness in their ears. Even if you call them to guidance, they will never be guided. 57 Your Lord is All-forgiving and All-merciful. Had He wanted to punish them for their sins, He would have been prompt to torment them. For their punishment there is an appointed time, after which there will be no way for them to escape. 58 We destroyed these communities when they went on doing wrong, and We appointed a time for their destruction. 59
