﴿ لِيَجْزِىَ ٱللَّهُ كُلَّ نَفْسٍۢ مَّا كَسَبَتْ ۚ إِنَّ ٱللَّهَ سَرِيعُ ٱلْحِسَابِ ﴾

“[And all shall be judged on that Day,] so that God may requite every human being for all that he has earned [in life]: verily, God is swift in reckoning!”

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.
