THUS, INDEED, have We given in this Qur'an many facets to every kind of lesson [designed] for [the benefit of] mankind. However, man is, above all else, always given to contention: 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 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 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 (as for) these towns, We destroyed them when they acted unjustly, and We have appointed a time for their destruction. 59
