Surah Fatir — Ayah 38 (35:38)
إِنَّ ٱللَّهَ عَٰلِمُ غَيۡبِ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِۚ إِنَّهُۥ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ ٣٨
English translation (Saheeh International)
Indeed, Allāh is Knower of the unseen [aspects] of the heavens and earth. Indeed, He is Knowing of that within the breasts.
Brief commentary
Allah knows all that is hidden in the heavens and earth. Nothing of that misses Him. He knows whatever His servants conceal in their chests, whether good or bad.
