Fussilat 41:22

Wama kuntum tastatiroona an yashhadaAAalaykum samAAukum wala absarukum walajuloodukum walakin thanantum anna Allahala yaAAlamu katheeran mimma taAAmaloon

And you were not covering [i.e., protecting] yourselves, lest your hearing testify against you or your sight or your skins, but you assumed that Allāh does not know much of what you do.

And you had not been hiding your selves (when committing sins) from your ears and your eyes and your skins that would bear witness against you, but you thought that Allah did not know much of what you did.
