فَلَمَّا نَسُوا۟ مَا ذُكِّرُوا۟ بِهِۦٓ أَنجَيْنَا ٱلَّذِينَ يَنْهَوْنَ عَنِ ٱلسُّوٓءِ وَأَخَذْنَا ٱلَّذِينَ ظَلَمُوا۟ بِعَذَابٍۭ بَـِٔيسٍۭ بِمَا كَانُوا۟ يَفْسُقُونَ
And when they forgot that whereof they had been reminded, We rescued those who forbade wrong, and visited those who did wrong with dreadful punishment because they were evil-livers.
