Based on this, whoever is not in direct contact with God and, without an intermediary, is not able to know about things that lead to his perfection and annihilation and things that result in His satisfactions and dissatisfactions has no choice but to search for one who has this ability, and he is called a “Prophet” in view of his bringing messages from God and logically known by declaring the Prophethood and presenting a thing that is inherently exclusive to God and none but He is able to present it; because presenting such a thing proves his connection with God, and that thing is called a “miracle”.
