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 Forbearing1 and Forgiving.
Allah, (may He be glorified), holds the heavens and the earth preventing them from vanishing and were they to vanish, hypothetically, there is none to hold them back from vanishing after Him, (may He be glorified). He is Forbearing, and does not rush to punish, Forgiving of the sins of those of His servants who repent.
