If the husband forgot saying "We are divorced" while being certain he did not divorce, and the wife remembers him uttering this phrase on the day she considered the message "Leave" a third divorce, does the divorce take place in this case?

If the husband says, "We are divorced," the matter divides into two scenarios: Either he is certain that he uttered it, and he intends to inform about a previous divorce, in which case the divorce does not occur. Or he is doubtful about uttering it, in which case the divorce does not occur, and the original state of marital bond remains. Therefore, the divorce has not taken place, the marital bond remains, and the wife is still under her husband's marital bond.
