رَبَّنَآ إِنَّكَ تَعْلَمُ مَا نُخْفِى وَمَا نُعْلِنُ ۗ وَمَا يَخْفَىٰ عَلَى ٱللَّهِ مِن شَىْءٍۢ فِى ٱلْأَرْضِ وَلَا فِى ٱلسَّمَآءِ
O our Lord! Truly You know what we conceal and what we reveal: for nothing whatsoever is hidden from Allah, whether on earth or in heaven!
Allah even knows the slightest glance of our eyes. He knows even the slightest thought that comes in our hearts. May Allah make us truly realize the fact that He is watching us and that He is all watchful.
Quran 14:38
