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 And naught prevented men from believing when the guidance came unto them, and seeking their Lord's forgiveness, but that the wont of the ancients should come upon them, or that the chastisement should come upon them face to face. 55 And We do not send apostles but as givers of good news and warning, and those who disbelieve make a false contention that they may render null thereby the truth, and they take My communications and that with which they are warned for a mockery. 56 Who is more wicked than the man who, when he is reminded by the revelations of his Lord, turns away from them and forgets (the consequence of) the deeds wrought by his own hands? We have laid veils over their hearts lest they understand the message of the Qur'an, and We have caused heaviness in their ears. Call them as you may to the Right Path, they will not be ever 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
