فليس كل قديم إلها
Not everything described as eternal is thereby a deity.
This corrects the objection from multiple eternal realities. Eternity does not by itself establish independent divine self-subsistence; divinity here concerns the necessary being that exists through itself.
The eternity of God's attributes is affirmed together with their inseparable relation to the divine essence. The inference “the attributes are eternal, therefore there are many gods” jumps to a conclusion without proving the intervening premise that each attribute is an independent essence.
