What should a wife do if her daughter accuses her husband of molesting her, while she is aware of his religious commitment, and strange signs appear on him during sleep, and he claims that he was married to "the other world" and that what emanated from him was beyond his control?

If the husband claims he did that against his will, he might be truthful or untruthful. If he is truthful, he should seek treatment through ruqyah (Islamic exorcism) himself or through someone else. The most important thing is to educate the daughter and guide her to avoid harassment from her father or anyone else, by dressing modestly in front of him, and by treating him as a stranger if she senses anything suspicious from him. She should not remove her hijab in his presence, nor allow him to be alone with her. She should not be left alone at home as long as there is fear for her safety. It is recommended to supplicate frequently and ask Allah for well-being.
