It is well known that the heavens and the earth, together with all that is within them, are entirely Allah’s creation. Thus, the praise fills the heavens and the earth, because created beings fill the heavens and the earth. This is the more fitting interpretation, because it enables a person to bear in mind that Allah is worthy of praise for every act He has done and every creature He has created.

The difference is evident between something filled with small bodies and something filled with large bodies, since that which is filled with large bodies will generally contain empty spaces. Consider, for example, a sa‘ of pressed dried curds formed into discs and a sa‘ of rice: you will find many gaps in the former but not in the latter.

His statement: “only” means: merely; that is, he does not add anything to it,
