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 nothing has prevented the people from believing when guidance came to them and from asking forgiveness of their Lord except that there [must] befall them the [accustomed] precedent of the former peoples or that the punishment should come [directly] before them. 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 And who is more unjust than he who is reminded of the communications of his Lord, then he turns away from them and forgets what his two hands have sent before? Surely We have placed veils over their hearts lest they should understand it and a heaviness in their ears; and if you call them to the guidance, they will not ever follow the right course in that case. 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 All the townships afflicted with scourge are before your eyes. When they committed wrong, We destroyed them. For the destruction of each We had set a definite term. 59
