Quran 67:13 — Kingship (Al-Mulk)

Whether you keep your utterances secret, or declare them, He is fully aware of the innermost thoughts.

[67:12] As for those who reverence their Lord, when alone in their privacy, they have attained forgiveness and a great recompense.

[67:14] Should He not know what He created? He is the Sublime, Most Cognizant.
