And verily We have displayed for mankind in this Qur'an all manner of similitudes, but man is more than anything contentious. 54 Nothing prevents people from believing when they are given guidance or from asking forgiveness of their Lord, but the fact that the fate of the previous peoples should befall them or to have the punishment come upon them face to face. 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 is more unjust than he who is reminded of the communications of his Lord, then he turns away from them and forgets what his two hands have sent before? Surely We have placed veils over their hearts lest they should understand it and a heaviness in their ears; and if you call them to the guidance, they will not ever follow the right course in that case. 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
