﴿ فَلَمَّا نَسُوا۟ مَا ذُكِّرُوا۟ بِهِۦٓ أَنجَيْنَا ٱلَّذِينَ يَنْهَوْنَ عَنِ ٱلسُّوٓءِ وَأَخَذْنَا ٱلَّذِينَ ظَلَمُوا۟ بِعَذَابٍۭ بَـِٔيسٍۭ بِمَا كَانُوا۟ يَفْسُقُونَ ﴾

“And thereupon, when those [sinners] had forgotten all that they had been told to take to. heart, We saved those who had tried to prevent the doing of evil, and overwhelmed those who had been bent on evildoing with dreadful suffering for all their iniquity;”

(And when they forgot that whereof they had been reminded) and when they left what they were commanded to do, (We rescued those who forbade wrong) i.e. catching fish on the Sabbath, (and visited those who did wrong) by catching fish on the Sabbath (with dreadful) a severe (punishment because they were evil-livers) because they were transgressors.
