20:7
وَإِن تَجْهَرْ بِٱلْقَوْلِ فَإِنَّهُۥ يَعْلَمُ ٱلسِّرَّ وَأَخْفَى
wa-in tajhar bil-qawli fa-innahu yaʿlamu l-sira wa-akhfā
Whatever you may say aloud, He knows what you keep secret and what is even more hidden.
And if you (O Muhammad صلى الله عليه وسلم) speak (the invocation) aloud, then verily, He knows the secret and that which is yet more hidden.
