Is the wife divorced if the husband swore to make her spend her night standing naked except for her underwear, and if he did not do so, she would be divorced, then he went to sleep and did not do that?

If your anger was so severe when uttering the divorce that you did not comprehend what you were saying, then the divorce does not occur due to theavement of accountability. However, if you comprehended what you were saying, then the divorce has occurred, and this is the view of the majority of scholars. If you had not divorced her before this time, or had divorced her only once, you can take her back before her waiting period (iddah) ends. But if you had divorced her twice before, she becomes unlawful for you and will not be lawful for you until she marries another man and he consummates the marriage with her, and then divorces her. A husband must treat his wife with kindness and not harm her.
