Does a husband's saying to his wife, "You are divorced, divorced, divorced," as a joke, while both are ignorant of its rulings, constitute a divorce, and is this considered an irrevocable divorce?

Divorce, whether serious or in jest, is equally binding. So, if a husband says to his wife, "You are divorced, divorced, divorced" in jest, the divorce takes effect. However, if the husband did not intend to address his wife with the divorce, but was merely recounting the words or trying to remember them, then divorce does not occur. If divorce does occur with this phrasing, it is considered a single divorce, whether uttered once or repeated, unless there was an intervening reconciliation or a new marriage contract. It is incumbent upon a Muslim to learn the rulings of his religion.
