And conceal your speech or publicize it; indeed, He is Knowing of (67:13)

Almuntakhab Fi Tafsir Alquran Alkarim

Whether you converse secretly and whisper the spoken words under your breath or you utter them loudly, He is well acquainted with all that is being said, and with all that you suggest secretly to the mind, and with all that the bosoms store of thoughts and feelings and all that they forge

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(67:13) Whether you speak in secrecy or aloud, (it is all the same to Allah). He even knows the secrets that lie hidden in the breasts of people. *20

And conceal your speech or publicize it; indeed, He is Knowing of meaning

*20) The address is to all human beings, whether they are believers or unbelievers. For the believer it contains the admonition that while living his life in the world he should always remember that not only his open and hidden deeds but even his secret intentions and innermost thoughts are not hidden from Allah; and for the unbeliever the warning that he may do whatever he may please fearless of God, but nothing that he does can remain un-noticed and unseen by Him.

تم خواہ چپکے سے بات کرو یا اونچی آواز سے (اللہ کے لیے یکساں ہے)، وہ تو دلوں کا حال تک جانتا ہے
