We have explained in various ways in this Quran, for the benefit of mankind, all kinds of examples, but man is most contentious. 54 There is nothing to prevent men from believing when the guidance has come to them, and asking for their Lord's forgiveness, unless they want the example of earlier people visited upon them, or the punishment to appear right before their eyes. 55 We never send apostles but to convey happy tidings, and to warn. But those who disbelieve contend with false arguments to nullify the truth. They make a mockery of My revelations and of what they had been warned. 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 And your Lord is the Oft Forgiver, the Merciful; if He seized them for their deeds, He would soon send the punishment upon them; but for them is an appointed time from which they will not find any refuge. 58 As for these habitations, We destroyed them only when they transgressed; even so We had fixed a time for their annihilation. 59
