كُلُّ شَيْءٍ هَالِكٌ إِلَّا وَجْهَهُ
Everything is perishing except Him.
Allah’s everlasting existence is intrinsic, whereas Paradise and Hell continue by His will. Listing created things that remain does not turn them into necessary or independently existing beings.
Actual perishing differs from the inherent possibility of perishing. Affirming a creature’s continued existence does not place it on an equal footing with its Creator.
