And verily We have displayed for mankind in this Qur'an all manner of similitudes, but man is more than anything 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 greater in evil than he who, when reminded of the verses of his Lord, turns away from them and forgets what his hands have sent before him? We have placed veils over their hearts lest they should understand it, and there is heaviness in their ears. Even if you call them to guidance, they will never be guided. 57 Your Lord is All-forgiving and All-merciful. Had He wanted to punish them for their sins, He would have been prompt to torment them. For their punishment there is an appointed time, after which there will be no way for them to escape. 58 And these towns – We destroyed them when they committed injustice, and We had set an appointed time for their destruction. 59
