We have explained in various ways all things to men in this Qur'an; but of all things man is most 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 And We send not the Envoys, but good tidings to bear, and warning. Yet do the unbelievers dispute with falsehood, that they may rebut thereby the truth. They have taken My signs, and what they are warned of, in mockery. 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 Your Lord is Forgiving, Owner of Mercy. Had it been His will to take them to task for what they earned, He would have hastened their punishment; but they have an appointed hour from which they will never escape. 58 And (as for) these towns, We destroyed them when they acted unjustly, and We have appointed a time for their destruction. 59
