Does divorce take effect if a man conditioned it on spying on his wife and her mother using a camera, then he spied on them without using a camera, and is this considered the fulfillment of the two conditions upon which the divorce was conditioned?

The scenario mentioned in the question does not constitute the suspension of divorce upon two conditions, but rather upon one condition: spying with a camera. If that occurs, the husband's oath is broken. If he spies without a camera, his oath is not broken, unless his intention was to prevent spying absolutely, regardless of the means. In that case, his oath is broken due to his intention. An example of suspending divorce upon two conditions is what is stated in Al-Fatawa al-Hindiyyah: "If I am absent from you for six months and my person and maintenance do not reach you during this period, then the matter of your divorce is in your hand." We caution against repeating questions that stem from obsessive doubts.
