We have indeed turned about for men in this Koran every manner of similitude; man is the most disputatious of things. 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 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 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 We destroyed these communities when they went on doing wrong, and We appointed a time for their destruction. 59
