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 We only send the messengers to bring good news and to give warning. 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 Thy Lord is the Forgiver, Full of Mercy. If He took them to task (now) for what they earn, He would hasten on the doom for them; but theirs is an appointed term from which they will find no escape. 58 And those cities - We destroyed them when they wronged, and We made for their destruction an appointed time. 59
