Then if the Messenger believes in him, the truthful one believes in what he brought and what he brought about the monotheism of God, which is his saying, “Say there is no god but God”

Or know that there is no god but God, so know that he is one in his divinity in terms of his saying, so know that There is no god but God, then that is called faith, and the believer in it is called to this extent a friend. If he looks at evidence that indicates the truth of his statement, then know that there is no god but God, and finds his monotheism after looking, so the Messenger is truthful in his saying, and God is truthful in saying to him, there is no god but God, then he is not a friend, and he is a believer. From evidence, he is knowledgeable. He has made clear to you the status of truthfulness, and that the truthful is the one with the light of faith that he finds necessary in the eye of his heart, like the light of sight that God placed in the sight, and the servant has no gain
