And verily We have displayed for mankind in this Qur'an all manner of similitudes, but man is more than anything 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 We only send the messengers to bring good news and to give warning. Those who deny use fallacious arguments to nullify the truth, treating My revelations and My warnings as a jest. 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 (all) those townships! We destroyed them when they did wrong, and We appointed a fixed time for their destruction. 59
