The following excerpt (footnote 1) is from Ascent to Felicity:

…Allah Most High exists, both preeternally and eternally, in an absolute manner, as opposed to the contingent existence of created things. That is, created things exist yet are bound by time, space, quantity, and quality, and this existence is contingent on the divine will. The existence of Allah Most High, however, is not bound by anything, and is not contingent on any external factor. It is absolute, and it transcends time, space, quantity, and quality (See Hadiyya 364; Bajuri 107, 134).
