And surely We have explained matters to people in the Qur'an in diverse ways, using all manner of parables. But man is exceedingly contentious. 54 And naught prevented men from believing when the guidance came unto them, and seeking their Lord's forgiveness, but that the wont of the ancients should come upon them, or that the chastisement should come upon them face to face. 55 We only send the messengers to bring good news and to give warning. Those who deny use fallacious arguments to nullify the truth, treating My revelations and My warnings as a jest. 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 as [was the case with all] those communities that We destroyed when they went on and on doing wrong: for We had set a time-limit for their destruction. 59
