Does a divorce take effect if the husband pronounces it while in a state of extreme, almost insane, anger, uttering it more than three times, and his wife is in her postpartum period? And how long is the waiting period (iddah) if it does take effect?

Divorcing a wife during menstruation or post-natal bleeding (nifas (definition)) is forbidden, but it is considered valid by most scholars, unless the husband was in a state of extreme anger that rendered him unaware of his actions, in which case the divorce does not occur. It is advisable to present such matters to a Sharia (definition) court or trusted scholars. The waiting period ('iddah (definition)) for divorce is three menstrual cycles for a menstruating woman, three months for a woman who has despaired of menstruating, and until delivery for a pregnant woman. The husband must control himself and avoid anger.
