Fatir 35:41

Inna Allaha yumsiku assamawatiwal-arda an tazoola wala-in zalatain amsakahuma min ahadin min baAAdihi innahu kanahaleeman ghafoora

Indeed, Allāh holds the heavens and the earth, lest they cease. And if they should cease, no one could hold them [in place] after Him. Indeed, He is Forbearing and Forgiving.

Undoubtedly, Allah holds back the heavens and the earth from leaving their existing state, and if they were to leave, there is none who can hold them back, except Him. Surely He is Forbearing, Most-Forgiving.
