﴿ لَّقَدْ كُنتَ فِى غَفْلَةٍۢ مِّنْ هَٰذَا فَكَشَفْنَا عَنكَ غِطَآءَكَ فَبَصَرُكَ ٱلْيَوْمَ حَدِيدٌۭ ﴾

“[and will be told:] “Indeed, unmindful hast thou been of this [Day of Judgment]; but now We have lifted from thee thy veil, and sharp is thy sight today!””

‘Verily in the world you were oblivious of this that has befallen you on this day; So now We have removed from you your covering We have done away with your oblivion by what you witness on this day and so your sight on this day is acute’ it is sharp able to perceive what you used to reject in the world.
