﴿ رَبَّنَآ إِنَّكَ تَعْلَمُ مَا نُخْفِى وَمَا نُعْلِنُ ۗ وَمَا يَخْفَىٰ عَلَى ٱللَّهِ مِن شَىْءٍۢ فِى ٱلْأَرْضِ وَلَا فِى ٱلسَّمَآءِ ﴾

“"O our Sustainer! Thou truly knowest all that we may hide [in our hearts] as well as all that we bring into the open:' for nothing whatever, be it on earth or in heaven, remains hidden from God.”
