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 naught hindereth mankind from believing when the guidance cometh unto them, and from asking forgiveness of their Lord unless (it be that they wish) that the judgment of the men of old should come upon them or (that) they should be confronted with the Doom. 55 The only reason for Our sending the Messengers is to give the human being the glad news of Our mercy and to warn him about Our wrath. The disbelievers argue by false means to refute the Truth. They mock My miracles and warnings. 56 And who is more unjust than one who is reminded of the verses of his Lord but turns away from them and forgets what his hands have put forth? Indeed, We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And if you invite them to guidance - they will never be guided, then - ever. 57 And your Lord is Forgiving, the Lord of Mercy; were He to punish them for what they earn, He would certainly have hastened the chastisement for them; but for them there is an appointed time from which they shall not find a refuge. 58 And (as for) these towns, We destroyed them when they acted unjustly, and We have appointed a time for their destruction. 59
