We have indeed turned about for men in this Koran every manner of similitude; man is the most disputatious of things. 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 never send apostles but to convey happy tidings, and to warn. But those who disbelieve contend with false arguments to nullify the truth. They make a mockery of My revelations and of what they had been warned. 56 Who is more unjust than he who, on being reminded of his Lord's revelations, turns away from them, and forgets the evil deeds he had committed in the past. Verily We have placed a covering on their hearts so that they do not understand, and a deafness in their ears so that however you may call them to guidance they will never be guided aright. 57 Thy Lord is the Forgiver, Full of Mercy. If He took them to task (now) for what they earn, He would hasten on the doom for them; but theirs is an appointed term from which they will find no escape. 58 And these cities! We destroyed them when they did wrong, and We had appointed for their destruction a tryst. 59
