And assuredly We have variously propounded in this Qur'an for mankind every kind of similitude; and man is of all things the most disputing. 54 And nothing prevents men from believing, now when the guidance (the Quran) has come to them, and from asking Forgiveness of their Lord, except that the ways of the ancients be repeated with them (i.e. their destruction decreed by Allah), or the torment be brought to them face to face? 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 Your Lord is All-Forgiving, full of mercy. Had He wished to take them to task for their doings, He would have hastened in sending His scourge upon them. But He has set for them a time-limit which they cannot evade. 58 As for these habitations, We destroyed them only when they transgressed; even so We had fixed a time for their annihilation. 59
