The Quran

108

يَستَخفونَ مِنَ النّاسِ وَلا يَستَخفونَ مِنَ اللَّهِ وَهُوَ مَعَهُم إِذ يُبَيِّتونَ ما لا يَرضىٰ مِنَ القَولِ ۚ وَكانَ اللَّهُ بِما يَعمَلونَ مُحيطًا

Muhammad Asad

They would conceal their doings from men; but from God they cannot conceal them - for He is with them whenever they devise, in the dark of night, all manner of beliefs¹ which He does not approve. And God indeed encompasses [with His knowledge] whatever they do.

Lit., "that of belief" (min al-qawl). It is to be remembered that the noun qawl does not denote merely "a saying" or "an utterance" (which is its primary significance): it is also employed tropically to denote anything that can be described as a "conceptual statement" - like an opinion, a doctrine, or a belief - and is often used in this sense in the Qur'an.
