We have explained in detail in this Qur'an, for the benefit of mankind, every kind of similitude: but man is, in most things, 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 send Our Messengers only to proclaim glad tidings and to give warning. But the unbelievers dispute with false arguments so that they may belie the truth. They have taken My verses and warnings in mockery. 56 Who is greater in evil than he who, when reminded of the verses of his Lord, turns away from them and forgets what his hands have sent before him?

Even if you call them to guidance, they will never be guided. 57 But thy Lord is the All-forgiving, full of mercy. If He should take them to task for that they have earned, He would hasten for them the chastisement; but they have a tryst, from which they will find no escape. 58 And (as for) these towns, We destroyed them when they acted unjustly, and We have appointed a time for their destruction. 59
