Does divorce take place if the wife says, "If you spy on me a second time, you are divorced forever," or "If I find out that you are spying on me a second time, you are divorced forever," and then she spies again without her husband's knowledge?

The husband's statement is a conditional divorce. If he intended divorce, it occurs upon the fulfillment of the condition. He must specify the condition he intends: Is it his knowledge of the spying, or the act of spying itself? If the husband did not intend divorce but rather a threat and prevention, the majority of scholars believe that divorce occurs upon the fulfillment of the condition, while others believe it is an oath and does not necessitate divorce. In case of doubt, the husband must be asked, and it is not permissible to remain with him, as the divorce may have already occurred.
