We have given various examples in this Quran for people to learn a lesson, but the human being is the most contentious creature. 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 Who is more unjust than he who, on being reminded of his Lord's revelations, turns away from them, and forgets the evil deeds he had committed in the past. Verily We have placed a covering on their hearts so that they do not understand, and a deafness in their ears so that however you may call them to guidance they will never be guided aright. 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 Such were the populations we destroyed when they committed iniquities; but we fixed an appointed time for their destruction. 59
