(Thwaha) 20 : 7
وَإِنْ تَجْهَرْ بِالْقَوْلِ فَإِنَّهُ يَعْلَمُ السِّرَّ وَأَخْفَى
And if you make words loud; then indeed He knows the secret as well as what is more hidden.
It is told in verses 67: 13-14: “You conceal your speech or publicize it; indeed He knows the status of the chests. Doesn’t He who created you know, while He is the Innermost-Knower, the Acquainted?” Lord is the One from whom nothing is hidden on earth and in heavens, He is the All-Hearing, All-Knowing as explained in verses 3: 5-6. See explanation 2: 255; 7: 205-206; 9: 51 and 16: 74.
