And surely We have explained matters to people in the Qur'an in diverse ways, using all manner of parables. But man is exceedingly 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 apostles save as bringers of glad tidings and warners; and those who disbelieve dispute with falsehood that they rebut thereby the truth; and they take My signs and that whereof they are warned as a mockery. 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 But thy Lord is the All-forgiving, full of mercy. If He should take them to task for that they have earned, He would hasten for them the chastisement; but they have a tryst, from which they will find no escape. 58 Such were the populations we destroyed when they committed iniquities; but we fixed an appointed time for their destruction. 59
