Al-Anbiya' - 21:110

إِنَّهُ يَعْلَمُ الْجَهْرَ مِنَ الْقَوْلِ وَيَعْلَمُ مَا تَكْتُمُونَ
[21:110]
Surely He knows what is spoken openly and He knows what you hide;
"It is He Who knows what is open in speech and what ye hide (in your hearts).
Lo! He knoweth that which is said openly, and that which ye conceal.
