فَلَمّا نَسوا ما ذُكِّروا بِهِ أَنجَينَا الَّذينَ يَنهَونَ عَنِ السّوءِ وَأَخَذنَا الَّذينَ ظَلَموا بِعَذابٍ بَئيسٍ بِما كانوا يَفسُقونَ

So, when they forgot what they had been reminded of, We saved those who prohibited wrong, and We seized those who did wrong with a severe punishment because they were transgressors.
