Do we fast three days, or do we await the fulfillment of the oath?

Divorce occurs by breaking an oath sworn by it or by making it conditional on an event, and no expiation (kaffara) is required for it. Sheikh al-Islam Ibn Taymiyyah held that if it was not intended to effect a divorce, then it falls under the ruling of an oath sworn by Allah, and expiation for an oath is required (feeding or clothing ten poor persons, or freeing a slave; if one cannot find these, then fasting), and it is permissible to perform the expiation before or after breaking the oath.
