And assuredly We have variously propounded in this Qur'an for mankind every kind of similitude; and man is of all things the most disputing. 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 do not send apostles but as givers of good news and warning, and those who disbelieve make a false contention that they may render null thereby the truth, and they take My communications and that with which they are warned for a 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 All-forgiving and All-merciful. Had He wanted to punish them for their sins, He would have been prompt to torment them. For their punishment there is an appointed time, after which there will be no way for them to escape. 58 As for these habitations, We destroyed them only when they transgressed; even so We had fixed a time for their annihilation. 59
