كُلُّ شَيْءٍ هَالِكٌ إِلَّا وَجْهَهُ لَهُ الْحُكْمُ وَإِلَيْهِ تُرْجَعُونَ
Everything is perishing except His presence. Judgment belongs to Him, and to Him you will be returned. (al-Qaṣaṣ 28:88)
The verse places the perishability of created things beside the permanence of Allah. Allah's own imperishability and the continued existence He grants Paradise and Hell are not the same kind of permanence.
