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 And We send not the messengers except as bringers of good tidings and warners. And those who disbelieve dispute by [using] falsehood to [attempt to] invalidate thereby the truth and have taken My verses, and that of which they are warned, in ridicule. 56 Who are more unjust than those who are reminded of the revelations of their Lord but have disregarded them and have forgotten their deeds? We have veiled their hearts and sealed their ears so that they cannot understand. Even if you call them to the right path, they will never accept guidance. 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 (as for) these towns, We destroyed them when they acted unjustly, and We have appointed a time for their destruction. 59
