﴿ فَقَدْ كَذَّبُوكُم بِمَا تَقُولُونَ فَمَا تَسْتَطِيعُونَ صَرْفًۭا وَلَا نَصْرًۭا ۚ وَمَن يَظْلِم مِّنكُمْ نُذِقْهُ عَذَابًۭا كَبِيرًۭا ﴾

“[Thereupon God will say:] “And now, they [whom you regarded as divine] have given the lie to all your [past] assertions, and you can neither ward off [your punishment] nor obtain any succour! For, whoever of you has committed [such] evil, him shall We cause to taste great suffering!””

(Thus they will give you the lie regarding what ye say, then ye) i.e. the disbelievers (can neither avert) avert the angels, and it is said this means: avert the idols from testifying against them or avert the chastisement from themselves (nor obtain help) backup. (And whoso among you doeth wrong) whoever among you, O Muslims, disbelieves; it is also said that this means: whosever of you, O disbelievers, remains firm in his disbelief, (We shall make him taste great torment) in the Fire.
