And verily We have displayed for mankind in this Qur'an all manner of similitudes, but man is more than anything contentious. 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 We only send the messengers to give Glad Tidings and to give warnings: But the unbelievers dispute with vain argument, in order therewith to weaken the truth, and they treat My Signs as a jest, as also the fact that they are warned! 56 And who could be more wicked than he to whom his Sustainer's messages are conveyed and who thereupon turns away from them, forgetting all [the evil] that his hands may have wrought? Behold, over their hearts have We laid veils which prevent them from grasping the truth, and into their ears, deafness; and though thou call them onto the right path, they will never allow themselves to be guided. 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 And those cities - We destroyed them when they wronged, and We made for their destruction an appointed time. 59
