Infikāk (separability) is the possibility of one thing existing apart from another. In one technical account, “otherness” involves the possibility that one of two things exists while the other does not.
Example: One created object can continue to exist when another no longer exists; they are distinct entities. The divine essence and its eternal attributes, however, are not two independently subsisting objects of this kind.
Divine knowledge is not an autonomous being apart from God, and God's essence is not described as existing without knowledge. Difference of meaning is affirmed, not independent separation. Applying this criterion indiscriminately raises further objections addressed in the discussion.
