We have explained in various ways all things to men in this Qur'an; but of all things man is most contentious. 54 And nothing prevents men from believing when the guidance comes to them, and from asking forgiveness of their Lord, except that what happened to the ancients should overtake them, or that the chastisement should come face to face with them. 55 And We send not the Envoys, but good tidings to bear, and warning. Yet do the unbelievers dispute with falsehood, that they may rebut thereby the truth. They have taken My signs, and what they are warned of, in 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 And thy Lord is the Forgiver, Owner of mercy. Were He to call them to account for that which they have earned; He would have hastened for them torment; but for them is a tryst beside which they cannot find a place to betake themselves to. 58 As for these habitations, We destroyed them only when they transgressed; even so We had fixed a time for their annihilation. 59
