Does the prohibition uttered by the husband in a state of extreme anger take effect?

The prohibition of a wife depends on the husband's intention. If he intended divorce, then it is a divorce. If he intended ẓihār (a form of divorce by injurious comparison), then it is ẓihār. If he intended an oath, or did not intend anything, then an expiation for an oath (kaffārat yamīn) is due. The evidence for this is Allah's saying: "O Prophet, why do you prohibit what Allah has made lawful for you, seeking to please your wives? And Allah is Forgiving and Merciful. Allah has already ordained for you the dissolution of your oaths. And Allah is your protector, and He is the Knowing, the Wise." If the phrasing mentioned indicates a promise, or if the husband was in a state of extreme anger, not knowing what he was saying, then nothing results from his words.
