It is Allāh who has created seven heavens and of the earth, the like of them.1 [His] command descends among them so you may know that Allāh is over all things competent and that Allāh has encompassed all things in knowledge.
Allah is the one who created the seven heavens. He also created seven earths just like He created seven heavens. His instructions related to matters of the universe and religion descend through the heavens. Perhaps this will make you realise that Allah is capable of everything, and that He be glorified has encompassed everything with His knowledge; nothing is hidden from Him in the heavens or the earth.
