Oneness in acts by saying that no other than God has an act like God’s act, for that involves that some other than God has an act, but that it is not like the act of God. That is false. God it is who is the creator of all acts. What comes from you by way of movement of the hand, when you strike Zayd, for example, is by the creation of God. He has said (Qur. 37, 99), “God created you, and what do ye do?” And another than God being possessor of an act is called external quantity in acts. So the unity necessary in God denies the five impossible quantities. Internal quantity in the essence makes the essence a compound of parts; external quantity means that there is an essence which resembles it. Internal quantity in the qualities is that God has two Powers, for example; external quantity in them means that someone else has a quality which resembles one of His qualities. External quantity in acts means that some other than God possesses an act. These five quantities deny the unity necessary in God. The meaning of quantity is number (_adad_). The proof that Unity is necessary in God is the existence of the world. If God had a partner (_sharik_) in divinity (_uluhiya_), the case could not be in doubt. Either they would agree on the existence of the world, in that one of them would say, “I will cause the world to exist,” and the other would say, “I will cause it to exist along with thee, that we may help one another in it.” Or they would disagree, and one of them would say, “I will cause the world to exist by my power,” and the other, “I will that the existence be lacking.” Then, if they agreed upon the existence of the world in that both of them together caused it to exist, and it existed through their action, that would necessarily involve the coincidence of two impressors upon one impression, which is impossible. And if they disagreed, it is plain that the will of one either would be carried out or it would not be carried out. If the will of one, rather than the other, is carried out, then the other whose will is not carried out must be weaker. But our hypothesis was that he was equal in divinity to the one whose will was carried out. So whenever weakness is established in the case of the one, it is established in the case of the other, for he is like the other. And if the wills of both are not carried out, they are both weak. And upon every alternative, that they agree or differ, the existence of a single thing of the world is impossible; because if they agree on its existence, there necessarily follows the coincidence of two impressors upon one impression if their will is carried out, and that is impossible. So the carrying out of their will is not affected, and it is not possible that a single thing of the world should come into existence then. And if they disagree and the will of one of them is carried out, the other is weak. But he is his like. So it is not possible that there should come into existence a single thing of this
