Does the divorce of an enraged person who is unaware of what he is saying take effect, especially if another person claims that the divorce occurred three times in different places while the wife is absent?

If the anger is so severe that consciousness is lost and one does not comprehend what is being said, then the divorce pronounced in that state does not take effect. The presence or absence of the wife does not affect the occurrence of the divorce. It is recommended to strive to rid oneself of severe anger, due to the Prophet’s (peace and blessings be upon him) saying: "Do not get angry."
