يَوْمَ يُكْشَفُ عَن سَاقٍ وَيُدْعَوْنَ إِلَى السُّجُودِ فَلَا يَسْتَطِيعُونَ
[68:42]
On the day when there shall be a severe affliction, and they shall be called upon to make obeisance, but they shall not be able,
The Day that the shin shall be laid bare, and they shall be summoned to bow in adoration, but they shall not be able,-
On the day when it befalleth in earnest, and they are ordered to prostrate themselves but are not able,
