Surah Qaf 50:22

لَّقَدْ كُنتَ فِى غَفْلَةٍ مِّنْ هَـٰذَا فَكَشَفْنَا عَنكَ غِطَآءَكَ فَبَصَرُكَ ٱلْيَوْمَ حَدِيدٌ

[It will be said], "You were certainly in unmindfulness of this, and We have removed from you your cover, so your sight, this Day, is sharp."

Translation: Saheeh International

Tafsir

‘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.
