القيام هو الاختصاص الناعت
Subsistence here means a distinctive relation of an attribute to what it qualifies.
On this technical account, the subsistence of a quality in the qualified is not always meant as literal spatial insertion. Divine attributes are affirmed in relation to the divine essence, without imagining a second external deity or a place containing God.
Self-subsistence, however, denotes nondependence upon another for existence. Thus “God subsists independently” and “divine attributes subsist with the divine essence” are not the same claim and must not be flattened into a single physical model.
