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 nothing prevents men from believing, now when the guidance (the Quran) has come to them, and from asking Forgiveness of their Lord, except that the ways of the ancients be repeated with them (i.e. their destruction decreed by Allah), or the torment be brought to them face to face? 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 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 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 cities! We destroyed them when they did wrong, and We had appointed for their destruction a tryst. 59
