Surah At-Taghabun — Ayah 4 (64:4)
يَعۡلَمُ مَا فِي ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِ وَيَعۡلَمُ مَا تُسِرُّونَ وَمَا تُعۡلِنُونَۚ وَٱللَّهُ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ ٤
English translation (Saheeh International)
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.
Brief commentary
He knows whatever is in the heavens and He knows whatever is on earth. He knows the actions that you conceal and those that you reveal. Allah is the Knower of the good or bad that the hearts contain. Nothing of that is hidden from Him.
