We have given various examples in this Quran for people to learn a lesson, but the human being is the most contentious creature. 54 Nothing prevented people from believing and seeking the forgiveness of their Lord when guidance came to them, unless they are waiting for the fate of the ancients to overtake them, or that the punishment should come upon them face to face. 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 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, full of mercy. Had He wished to take them to task for their doings, He would have hastened in sending His scourge upon them. But He has set for them a time-limit which they cannot evade. 58 And these towns – We destroyed them when they committed injustice, and We had set an appointed time for their destruction. 59
