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 We send Our Messengers only to proclaim glad tidings and to give warning. But the unbelievers dispute with false arguments so that they may belie the truth. They have taken My verses and warnings in mockery. 56 And who is more unjust than one who is reminded of the verses of his Lord but turns away from them and forgets what his hands have put forth? Indeed, We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And if you invite them to guidance - they will never be guided, then - ever. 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 And these cities! We destroyed them when they did wrong, and We had appointed for their destruction a tryst. 59
