هَـٰذَا يَوْمُ ٱلْفَصْلِ ٱلَّذِى كُنتُم بِهِۦ تُكَذِّبُونَ Qur’an As-Saffat (37:21)Hatha yawmu alfasli allathee kuntum bihi tukaththiboona
See note [6] on 77:13 .
The Day of Judgment is the day of sorting out. Cf. xxxvi. 59. Good and evil will finally be separated, unlike the apparently inexplicable conditions in the present probationary life, when they seem to be mixed together.
