﴿ أَفَأَمِنُوٓا۟ أَن تَأْتِيَهُمْ غَٰشِيَةٌۭ مِّنْ عَذَابِ ٱللَّهِ أَوْ تَأْتِيَهُمُ ٱلسَّاعَةُ بَغْتَةًۭ وَهُمْ لَا يَشْعُرُونَ ﴾

“Do they, then, feel free from the fear that there might fall upon them the overwhelming terror of God's chastisement, or that the Last Hour might come upon them of a sudden, without their being aware [of its approach]?”

a pall of God's chastisement, a veil, issuing from a deeply-rooted dark configuration, that obstructs their preparedness from receiving perfection; or the coming, of the minor resurrection, upon them suddenly, while they are unaware, of the light of unveiling and the affirmation of Oneness and so their veil is not lifted and they remain forever veiled.
