Surah Al-Qiyamah — Ayah 2 (75:2)
وَلَآ أُقۡسِمُ بِٱلنَّفۡسِ ٱللَّوَّامَةِ ٢
English translation (Saheeh International)
And I swear by the reproaching soul1 [to the certainty of resurrection].
- - i.e., that of the believer, which blames him when he falls into sin or error.
Brief commentary
He took an oath by the pure soul that reproaches its owner for falling short in righteous deeds and for doing wrong deeds. He took an oath by these two things that He will certainly resurrect people for reckoning and recompense.
