We have explained in various ways in this Quran, for the benefit of mankind, all kinds of examples, but man is most contentious. 54 What is it that prevented mankind from believing when the guidance came to them, and from asking forgiveness of their Lord, except that they would like to be treated as the nations of yore, or that they would like to see the scourge come upon 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 Most forgiving, full of Mercy. If He were to call them (at once) to account for what they have earned, then surely He would have hastened their punishment: but they have their appointed time, beyond which they will find no refuge. 58 And these towns (population, 'Ad, Thamud, etc.) We destroyed when they did wrong. And We appointed a fixed time for their destruction. 59
