وَأَنَّ سَعْيَهُۥ سَوْفَ يُرَىٰ
Wa anna sa'yahoo sawfa yuraa
that his labour will be seen
and that his striving will be seen,
The passive here leaves the viewer unnamed, and commentators filled it in differently: shown to the person on the day itself, displayed before others, or present in God's knowledge all along. Sawfa sets the seeing at a distance from the doing. The verse after it opens with thumma, which marks an interval, so the display and the repayment are staged as separate moments.
