Surah At Tawbah Tafseer

أَلَمْ يَعْلَمُواْ أَنَّ اللّهَ يَعْلَمُ سِرَّهُمْ وَنَجْوَاهُمْ

Know they not that Allah knows their secret ideas, and their Najwa,

Allah states that He knows the secret and what is more hidden than the secret. He has full knowledge of what is in their hearts, even when they pretend that they will give away alms, if they acquire wealth, and will be grateful to Allah for it. Truly,

Allah knows them better than they know themselves, for He is the All-Knower of all unseen and apparent things, every secret, every session of counsel, and all that is seen and hidden.

وَأَنَّ اللّهَ عَلَّمُ الْغُيُوبِ

and that Allah is the All-Knower of things unseen
