Furthermore, even if the heavens are rolled up, become like molten metal, and are transformed from their present form, this does not entail their ceasing to exist or being destroyed. Rather, their underlying substance remains as they are transformed from one state to another, as Allah Most High says:

“On the Day when the earth is changed to another earth, and the heavens likewise.”

Even when they are changed, there will still be an enduring heaven and an enduring earth. And Allah knows best.
