Is divorce obligatory in a void marriage that occurred due to obsessive-compulsive disorder, which causes a person to utter phrases such as marrying off his mother or his married sister to so-and-so, knowing that this utterance happens between himself and himself?

Do not pay attention to such thoughts and imaginations, for they are whisperings from Satan that must be ignored and not indulged. There is no divorce or marriage in what the one afflicted with whispers imagines. Treatment for this obsessive-compulsive disorder should be sought.
