We have explained in various ways in this Quran, for the benefit of mankind, all kinds of examples, but man is most contentious. 54 And nothing prevents men from believing when the guidance comes to them, and from asking forgiveness of their Lord, except that what happened to the ancients should overtake them, or that the chastisement should come face to face with them. 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 one who, when reminded of the signs of his Lord, turns away from them and forgets what his hands have sent forward? We have put covers on their hearts so as not to understand the Qur’an, and deafness in their ears; and even if you call them to guidance, they will never attain the right path. 57 Yet, [withal,] thy Sustainer is the Truly-Forgiving One, limitless in His grace. Were He to take them [at once] to task for whatever [wrong] they commit, He would indeed bring about their speedy punishment [then and there]: but nay, they have a time-limit beyond which they shall find no redemption 58 And those cities, We destroyed them when they did evil, and appointed for their destruction a tryst. 59
