And certainly We have explained in this Quran every kind of example, and man is most of all given to contention. 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 apostles save as bringers of glad tidings and warners; and those who disbelieve dispute with falsehood that they rebut thereby the truth; and they take My signs and that whereof they are warned as a mockery. 56 And who doth greater wrong than he who is admonished with the signs of His Lord yet turneth away from them and forgetteth that which his hands have sent forth? Verily We have set up veils over their hearts lest they should understand it, and in their ears a heaviness; and if thou callest them to the guidance, lo! they will not let themselves be guided ever. 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 (population, 'Ad, Thamud, etc.) We destroyed when they did wrong. And We appointed a fixed time for their destruction. 59
