Al-Haqqah - 69:18

يَوْمَئِذٍ تُعْرَضُونَ لَا تَخْفَى مِنكُمْ خَافِيَةٌ
[69:18]
On that day you shall be exposed to view-- no secret of yours shall remain hidden.
That Day shall ye be brought to Judgment: not an act of yours that ye hide will be hidden.
On that day ye will be exposed; not a secret of you will be hidden.
