However, man is, above all else, always given to contention: 54 And what is there to keep back men from believing, now that Guidance has come to them, nor from praying for forgiveness from their Lord, but that (they ask that) the ways of the ancients be repeated with them, or the Wrath be brought to 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 doth more wrong than one who is reminded of the Signs of his Lord, but turns away from them, forgetting the (deeds) which his hands have sent forth? Verily We have set veils over their hearts lest they should understand this, and over their ears, deafness, if thou callest them to guidance, even then will they never accept guidance. 57 But your Lord is forgiving, full of benevolence. If He had pleased to punish them for their doings He would have punished them immediately. But a term is fixed for them from which they will find no escape. 58 And those cities - We destroyed them when they wronged, and We made for their destruction an appointed time. 59
