We have explained in detail in this Qur'an, for the benefit of mankind, every kind of similitude: but man is, in most things, contentious. 54 And what prevented men from accepting faith when guidance came to them, and from asking forgiveness from their Lord except that the tradition of the former nations come upon them or that they confront various kinds of punishments? 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 one who is reminded of the verses of his Lord but turns away from them and forgets what his hands have put forth? Indeed, We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And if you invite them to guidance - they will never be guided, then - ever. 57 Your Lord is the Forgiving One, the possessor of mercy. If He had to take them to task for the wrongs they have done, He would have hastened their punishment. They have an appointed time beyond which there will be no escape for them. 58 And these cities! We destroyed them when they did wrong, and We had appointed for their destruction a tryst. 59
