(Ibrahim) 14 : 38
رَبَّنَا إِنَّكَ تَعْلَمُ مَا نُخْفِي وَمَا نُعْلِنُ ۗ وَمَا يَخْفَىٰ عَلَى اللَّهِ مِنْ شَيْءٍ فِي الْأَرْضِ وَلَا فِي السَّمَاءِ
Our Lord, indeed You know what we hide and what we declare, and nothing is hidden from Lord Allah on the earth or in the heavens.
See explanation 2: 255, 284; 3: 5 and 9: 51.
