«الوجودية اللادائمة»
The existential non-permanent modality.
«وهي المطلقة العامة مع قيد اللادوام بحسب الذات»
It is the generally absolute proposition plus non-permanence with respect to the subject itself.
In the existential non-necessary kind, the first part affirms actuality and the second denies necessity. Here actuality remains, but the second clause denies permanence.
These are two distinct modes: one rejects essential necessity, and the other rejects persistence over the subject's existence.
