Quran At-Taghabun 64:4
يَعۡلَمُ مَا فِي ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِ وَيَعۡلَمُ مَا تُسِرُّونَ وَمَا تُعۡلِنُونَۚ وَٱللَّهُ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ ٤
Translation
He knows what is within the heavens and earth and knows what you conceal and what you declare. And Allāh is Knowing of that within the breasts.
