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 We never send apostles but to convey happy tidings, and to warn. But those who disbelieve contend with false arguments to nullify the truth. They make a mockery of My revelations and of what they had been warned. 56 And who does greater evil than he who, being reminded of the signs of his Lord, turns away from them and forgets what his hands have forwarded? Surely We have laid veils on their hearts lest they understand it, and in their ears heaviness; and though thou callest them to the guidance, yet they will not be guided ever. 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 And these cities! We destroyed them when they did wrong, and We had appointed for their destruction a tryst. 59
