We have explained in detail in this Qur'an, for the benefit of mankind, every kind of similitude: but man is, in most things, contentious. 54 Nothing prevents people from believing when they are given guidance or from asking forgiveness of their Lord, but the fact that the fate of the previous peoples should befall them or to have the punishment come upon them face to face. 55 We send not the messengers save as bearers of good news and warners. Those who disbelieve contend with falsehood in order to refute the Truth thereby. And they take Our revelations and that wherewith they are threatened as a jest. 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 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 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
