What is the ruling on one who swore an oath of triple divorce upon his wife that "she will not do anything in this apartment," intending to end a dispute, and then she did do something in the apartment?

Swearing an oath by divorce falls under the ruling of conditional divorce, and it takes effect upon the realization of the sworn-upon condition, unequivocally, according to the majority of jurists. Furthermore, uttering the triple divorce in a single phrase results in a triple divorce according to the majority. Consequently, a triple divorce has occurred, and the wife has become irrevocably separated (baynunah kubra).
