The Holy Quran 28:69 — Surah Al-Qasas
Arabic text
وَرَبُّكَ يَعْلَمُ مَا تُكِنُّ صُدُورُهُمْ وَمَا يُعْلِنُونَ
Translation
Your Rabb knows what (beliefs and intentions) their hearts conceal (hide) and what (actions) they make public (reveal) (Therefore, nothing can be hidden from Him).
Tafsir (excerpt) — Tafsir Usmani
The all-encompassing knowledge of Almighty Allah: that is, the corrupt beliefs or evil intentions they hold in their hearts, and the deeds they do with tongue, hands, feet and so on, are all within the knowledge of Almighty Allah. He alone is aware of the hidden aptitude and capacity of every person, and He will deal [with him] accordingly.
