And verily We have displayed for mankind in this Qur'an all manner of similitudes, but man is more than anything contentious. 54 And what prevented men from accepting faith when guidance came to them, and from asking forgiveness from their Lord except that the tradition of the former nations come upon them or that they confront various kinds of punishments? 55 We raise Messengers only to give good news and to warn. But the unbelievers resort to falsehood in order to rebut the truth with it, and scoff at My revelations and My warnings. 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 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
