Would she be divorced from her husband if he said to her: "If I [he repeated her vulgar words], then you are divorced," knowing that this is the third divorce?

The issue has details. If the wife is told, "If you are as you mentioned, then you are divorced," as a form of immediate consequence, the divorce occurs instantly. However, if it is in the form of a condition, then the matter depends on the fulfillment of the description. It is advised to consult scholars directly or refer to Islamic centers to decide on the matter. It is recommended for spouses to live together amicably, avoid allowing Satan to come between them, and strive to avoid words of divorce, resolving problems through other legitimate means.
