Did the triple divorce occur, bearing in mind that the last divorce took place during menstruation, and what is the ruling on the husband's statement that he was angry when uttering the divorce, and is the divorce considered an irrevocable major divorce?

The ruling of a judge or the fatwa (religious edict) of a mufti does not change the reality. So, if the husband lied to the Dar al-Ifta (House of Fatwa) and they issued a fatwa based on what he said, deeming you still under his marital bond, you are not truly under his marital bond, and it is impermissible for him to enjoy you. Rather, it is obligatory to separate from him and seek redemption from the marriage. Anger does not prevent the occurrence of divorce if the person experiencing it is aware of what he is saying. Divorce pronounced during menstruation is valid according to the preponderant opinion.
