We have set forth for people in this Koran all manner of parables; the human is the most disputatious of things. 54 What is it that prevented mankind from believing when the guidance came to them, and from asking forgiveness of their Lord, except that they would like to be treated as the nations of yore, or that they would like to see the scourge come upon them face to face? 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 Forgiving, Owner of Mercy. Had it been His will to take them to task for what they earned, He would have hastened their punishment; but they have an appointed hour from which they will never escape. 58 And those cities - We destroyed them when they wronged, and We made for their destruction an appointed time. 59
