We have indeed turned about for men in this Koran every manner of similitude; man is the most disputatious of things. 54 And what is there to keep back men from believing, now that Guidance has come to them, nor from praying for forgiveness from their Lord, but that (they ask that) the ways of the ancients be repeated with them, or the Wrath be brought to 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 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 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 Such were the populations we destroyed when they committed iniquities; but we fixed an appointed time for their destruction. 59
