Az-Zumar • EN-TAFSIR-IBN-ABBAS
﴿ أَن تَقُولَ نَفْسٌۭ يَٰحَسْرَتَىٰ عَلَىٰ مَا فَرَّطتُ فِى جَنۢبِ ٱللَّهِ وَإِن كُنتُ لَمِنَ ٱلسَّٰخِرِينَ ﴾
“lest any human being should say [on Judgment Day], “Alas for me for having been remiss in what is due to God, and for having been indeed one of those who scoffed [at the truth]!””
(Lest any soul should say) so that no soul should say: (Alas, my grief) I am remorseful (that I was unmindful of Allah) that I have left the obedience of Allah, (and I was indeed among the scoffers) and I was indeed among those who mocked the Scripture and Messenger!
