What are the rational and scriptural proofs for the necessity of God Almighty’s existence and His possessing attributes of absolute perfection, and the impossibility of His being characterized by any deficiency, along with an explanation that deficiency indicates contingency and creation, and the impossibility of there being multiple necessarily existent beings? And why, when assuming multiple necessarily existent beings, would there be dominance, subjugation, and strife among them instead of understanding and reconciliation? And why would each god not have his own creation and domain without interference from the other, despite God’s command for reconciliation and the vastness of His wisdom? And does wisdom necessitate that there be no partnership in creation among gods, and that each god has his own creation and universe to manage as he pleases without interference?

Allah Almighty, "the Necessarily Existent," is characterized by all attributes of perfection and free from all attributes of imperfection. The multiplicity of the Necessarily Existent is impossible. The assumption of multiple deities is false and absurd, because with it, the unity of will in everything cannot exist. If one of them wills something, and the other wills its opposite, whose will shall be carried out? The premise is that the will of a deity is carried out. Ibn Atiyah says: "It is impossible for a created part to be subject to two or more powers, or for two deities to differ in will: for it is impossible for both their wills to be carried out, and impossible for them to be impotent. So, if the will of one is carried out, then He is the Most High and the other is not a deity. If it is said: 'We assume they do not differ in will!' It is said: 'That is by assumption, and if the disbelievers allow it, then the argument is established; for what is assumed to be permissible, what is assumed to occur will follow.'"
