Does the divorce of a sleeping person who hears "I divorce you" in his sleep, and does not know whether his tongue uttered it or not, take effect?

If a husband did not intend to utter a divorce but it slipped from his tongue inadvertently, then nothing is binding upon him, whether he was awake or asleep, because intention is a pillar of divorce. The divorce of a person afflicted by Waswas (obsessive whispering) also does not take effect. It is advisable to turn away from these whisperings because they are from Satan, and to be diligent in performing Ruqyah (definition) Shar'iyyah (Islamic exorcism/healing).
