And certainly We have explained in this Quran every kind of example, and man is most of all given to contention. 54 And nothing prevents men from believing, now when the guidance (the Quran) has come to them, and from asking Forgiveness of their Lord, except that the ways of the ancients be repeated with them (i.e. their destruction decreed by Allah), or the torment be brought to them face to face? 55 And We do not send apostles but as givers of good news and warning, and those who disbelieve make a false contention that they may render null thereby the truth, and they take My communications and that with which they are warned for a mockery. 56 Who is more wicked than the man who, when he is reminded by the revelations of his Lord, turns away from them and forgets (the consequence of) the deeds wrought by his own hands? We have laid veils over their hearts lest they understand the message of the Qur'an, and We have caused heaviness in their ears. Call them as you may to the Right Path, they will not be ever guided aright. 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 We destroyed these communities when they went on doing wrong, and We appointed a time for their destruction. 59
