And certainly We have explained in this Quran every kind of example, and man is most of all given to contention. 54 What prevents people from having faith when guidance comes to them or from asking for forgiveness from their Lord before they face the kind of torment that the ancient people experienced or a new form of torment. 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 are more unjust than those who are reminded of the revelations of their Lord but have disregarded them and have forgotten their deeds? We have veiled their hearts and sealed their ears so that they cannot understand. Even if you call them to the right path, they will never accept guidance. 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 (all) those townships! We destroyed them when they did wrong, and We appointed a fixed time for their destruction. 59
