The Holy Quran 57:6 — Surah Al-Hadid

Arabic text

يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ ۚ وَهُوَ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ

Translation

He enters the night into the day and the day into the night. He has knowledge of the secrets of the heart.

Tafsir (excerpt) — Tafsir Usmani

That is, the intentions and resolves that arise in hearts, or the passing thoughts and whisperings that come [into them], are also not outside His knowledge.
