Surah Ibrahim — Ayah 51 (14:51)
لِيَجۡزِيَ ٱللَّهُ كُلَّ نَفۡسٖ مَّا كَسَبَتۡۚ إِنَّ ٱللَّهَ سَرِيعُ ٱلۡحِسَابِ ٥١
English translation (Saheeh International)
So that Allāh will recompense every soul for what it earned. Indeed, Allāh is swift in account.
Brief commentary
Allah will recompense each soul for the good and evil it did, and Allah is swift in taking account. He will account for the first ones on a single day, and His accounting for one will not distract Him from accounting for another.
