Does a divorce occur when a husband says "You are divorced" with the intention of threatening, and what is the ruling on repeating this phrase with the aforementioned intention, and is the wife considered forbidden to him after repeating these phrases with different intentions?

Divorce was legislated for the benefit of the spouses when reconciliation between them becomes impossible, and not as a means of threat. If the husband says to his wife, "If you do not do such-and-such, then you are divorced," and she complies, she is not divorced. However, if he says, "You are divorced," and he understands what he is saying, then his wife is divorced from him, even if he claims he did not intend divorce. This is by consensus of the scholars, because an explicit divorce does not require intention.

If the husband continued to cohabit with his wife after the first and second divorces, this is considered a return (revocation of divorce) to her. If he divorces her a third time, she becomes irrevocably separated from him by a major divorce (baynunah kubra). However, if he did not return to her until her waiting period (iddah) ended, and then resumed cohabiting with her, he is considered an adulterer, and any subsequent divorce issued by him would be invalid due to the wife's separation (baynunah).
