And certainly We have explained in this Quran every kind of example, and man is most of all given to contention. 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 the Envoys, but good tidings to bear, and warning. Yet do the unbelievers dispute with falsehood, that they may rebut thereby the truth. They have taken My signs, and what they are warned of, 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 as [was the case with all] those communities that We destroyed when they went on and on doing wrong: for We had set a time-limit for their destruction. 59
