Know that the essence from both sides cannot be required because it exists, but rather it is related to the non-existent request in order for it to exist, so nothing is called except the non-existent because supplication is a request and the request is the same as the will, and the will is only related to the non-existent. We said, and so it happened, for nothing appeared from this called except the answer and it was non-existent despite the fact that The essence of the one being called for what he is being called to exists exists, so the answer appeared from the one being called after it had not existed, because the answer does not occur except after the supplication of a supplicant, and this non-existent and established being called is not valid for its existence from the essence of the called, but rather it is valid in the essence of the called if the called is from the world, so he lacks the caller saying to him, “Be,” then The person being called is a response to his command
