What is the ruling on repeating the word of divorce in a state of extreme anger accompanied by quarreling and insults?

If anger overwhelms the husband's mind to the point where he becomes like a madman, not realizing what he is saying, then his divorce does not take effect. However, if anger does not cause him to lose his mind, then his divorce is valid. If the repetition of the word "divorce" is merely for emphasis, only one divorce takes effect. But if he intends to effect more than one divorce, then all of his divorces take effect, according to the majority of scholars.
