We have indeed turned about for men in this Koran every manner of similitude; man is the most disputatious of things. 54 for, what is there to keep people from attaining to faith now that guidance has come unto them, and from asking their Sustainer to forgive them their sins - unless it be [their wish] that the fate of the [sinful] people of ancient times should befall them [as well,] or that the [ultimate] suffering should befall them in the hereafter? 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, 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 those cities - We destroyed them when they wronged, and We made for their destruction an appointed time. 59
