"يعلم ما في السموات والأرض ويعلم ما تسرون وما تعلنون والله عليم بذات الصدور".
He knows whatever is in the heavens and He knows whatever is on earth. He knows the actions that you conceal and those that you reveal. Allah is the Knower of the good or bad that the hearts contain. Nothing of that is hidden from Him.
