Does divorce occur with the saying "divorce be upon me" or "my wife is forbidden to me" or "she is divorced if she becomes jealous of me" if these phrases are said with intention only without uttering them, or by moving the tongue without sound?

As long as you did not utter the oath while in a state of choice and awareness, but rather spoke to yourself about it without uttering it, then no divorce has occurred, and nothing is binding upon you because of it. Uttering the divorce, which is subject to legal consequence, must involve the movement of the tongue and lips so that letters are produced. Therefore, turn away from these whispers and be wary of indulging them.
