We have explained in various ways in this Quran, for the benefit of mankind, all kinds of examples, but man is most contentious. 54 for, what is there to keep people from attaining to faith now that guidance has come unto them, and from asking their Sustainer to forgive them their sins - unless it be [their wish] that the fate of the [sinful] people of ancient times should befall them [as well,] or that the [ultimate] suffering should befall them in the hereafter? 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 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 Most Forgiving, Owner of Mercy. Were He to call them to account for what they have earned, then surely, He would have hastened their punishment. But they have their appointed time, beyond 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
