لِيَجْزِىَ ٱللَّهُ كُلَّ نَفْسٍۢ مَّا كَسَبَتْ ۚ إِنَّ ٱللَّهَ سَرِيعُ ٱلْحِسَابِ
So that Allah will recompense every soul for what it earned. Indeed, Allah is swift in account.
that God may requite li-yajziya is semantically connected to the verb barazū ‘they shall come forth’ every soul for what it has earned of good and evil. Truly God is swift at reckoning — He shall reckon with all creatures in about half a day of the days of this world as one hadīth states to that effect.
