Does divorce take effect if the tongue moves, uttering the divorce formula—unintentionally—while the lips are sealed and the mouth is closed?

These doubts do not result in divorce. It is clear from the question that the questioner suffers from obsessive whispers (waswasah). She must disregard them and pay no attention to them, for indulging in obsessions leads to great evil. She must seek help from Allah, not despair, and occupy her time with what benefits her in her religion and worldly life. It is recommended to consult the psychological counseling section on the website.
