لأنها ليست غير الذات، كما أنها ليست عينها
For they are not other than the Essence, just as they are not simply identical to it.
This is specialized Sunni kalām terminology. 'Other' does not here mean a fully separate, independently existing thing detachable from the divine essence. Conversely, denying simple identity does not deny the real meanings of knowledge, power, and will; these attributes have distinct intelligible significations.
Treating 'same' and 'other' as ordinary, unqualified everyday opposites creates a false contradiction. The intended point is that attributes of perfection are affirmed without turning them into detached created entities or newly arising accidents.
