And certainly We have explained in this Quran every kind of example, and man is most of all given to contention. 54 And naught hindereth mankind from believing when the guidance cometh unto them, and from asking forgiveness of their Lord unless (it be that they wish) that the judgment of the men of old should come upon them or (that) they should be confronted with the Doom. 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 doth greater wrong than he who hath been reminded of the revelations of his Lord, yet turneth away from them and forgetteth what his hands send forward (to the Judgment)? Lo! on their hearts We have placed coverings so that they understand not, and in their ears a deafness. And though thou call them to the guidance, in that case they can never be led aright. 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 as [was the case with all] those communities that We destroyed when they went on and on doing wrong: for We had set a time-limit for their destruction. 59
