Surah Fatir, ayah 38

35:38

إِنَّ ٱللَّهَ عَٰلِمُ غَيۡبِ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِۚ إِنَّهُۥ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ ٣٨

Innallāha 'ālimu ghaybis-samāwāti wal-ardi innahū 'alīmu bidhātis-sudūr

Indeed, Allāh is Knower of the unseen [aspects] of the heavens and earth. Indeed, He is Knowing of that within the breasts.
