Is a person held accountable for the sound of air expelled from his nose that resembles saying "I agree" in the context of imagining divorce, knowing that the tongue did not move? And what should one suffering from obsessive-compulsive disorder do regarding the compulsive divorce obsessions that cause him severe distress and disrupt his life?

We advise you to seek refuge in Allah and supplicate to Him. You should also perform ruqyah (definition) (Islamic exorcism) and continue treatment with specialized doctors. We recommend that you disregard and resist any thoughts that come to your heart regarding divorce, for if a person reaches this state of obsessive whispering, their divorce does not take effect. Be sure to resume your life with your wife and friends normally.
