We have explained in various ways all things to men in this Qur'an; but of all things man is most 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 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 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 And your Lord is Most Forgiving, Owner of Mercy. Were He to call them 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 escape. 58 And these towns – We destroyed them when they committed injustice, and We had set an appointed time for their destruction. 59
