أَن تَقُولَ نَفۡسٞ يَٰحَسۡرَتَىٰ عَلَىٰ مَا فَرَّطتُ فِي جَنۢبِ ٱللَّهِ وَإِن كُنتُ لَمِنَ ٱلسَّٰخِرِينَ ٥٦
Lest a soul should say,1 "Oh, [how great is] my regret over what I neglected in regard to Allāh and that I was among the mockers."
Translation: Saheeh International (English)
1 On the Day of Resurrection.
Each word's meaning and sound
Act now to avoid the soul's extreme regret when it will declare on the day of resurrection: Alas my grief over my negligence in my duty to Allah by the disbelief and sins committed, and the mocking of the people of faith and obedience in the world.
