(1) He knows what penetrates into the earth and what emerges from it and what descends from the heaven and what ascends therein. And He is the Merciful, the Forgiving.

(2) It is He who created the heavens and earth in six days and then established Himself above the Throne. He knows what penetrates into the earth and what emerges from it and what descends from the heaven and what ascends therein; and He is with you wherever you are. And Allah, of what you do, is Seeing.
