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 naught preventeth mankind from believing when the guidance hath come unto them, and from asking foregiveness of their Lord, but that there may come unto them the dispensation of the ancients, or that the torment may come unto them face to face. 55 We send Our Messengers only to proclaim glad tidings and to give warning. But the unbelievers dispute with false arguments so that they may belie the truth. They have taken My verses and warnings 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 But your Lord is Most forgiving, full of Mercy. If He were to call them (at once) to account for what they have earned, then surely He would have hastened their punishment: but they have their appointed time, beyond which they will find no refuge. 58 And these towns – We destroyed them when they committed injustice, and We had set an appointed time for their destruction. 59
