What is the ruling regarding a wife who left the home after her husband swore, saying: "By Allah, if you leave this house, you are divorced by three and you will never return to this house"?

This is a suspended triple divorce contingent upon the wife leaving the house. So, if the wife leaves, a triple divorce occurs, according to what is held as authoritative by us, whether the divorce was intended or the intention was to threaten or prevent her. The pronouncement of "triple" results in a triple divorce according to the majority of scholars.
