What is the ruling regarding the husband's oath of divorce, saying, "Divorce be upon me if you bring another medicine, you will not stay in it," after his wife had bought medicine for his mother without consulting a doctor, then bought another medicine with a medical prescription, and a third medicine without a medical prescription, forgetting his oath?

The majority of scholars hold that a divorce oath results in divorce if the sworn-upon condition occurs, and this is the fatwa we adopt. However, Sheikh al-Islam Ibn Taymiyyah is of the view that an oath of divorce not intended to effect divorce but rather for threat or emphasis on a matter, is treated like an oath. Thus, if the sworn-upon condition occurs, the swearer must pay expiation for an oath, and no divorce takes place.
