Does a divorce issued by a husband who is suffering from psychological disorders and taking medication, and who was under severe psychological pressure, take effect, especially since the wife had not yet performed ghusl after the end of her menstrual period when the divorce was issued?

As long as the husband explicitly uttered the divorce (talaq (definition)) while being aware and not overcome by his emotions, then his divorce is effective. The intensity of his anger or his emotional distress does not prevent its effectiveness. Divorcing a menstruating woman is forbidden, but it is effective according to most scholars. If the bleeding stops, then divorce becomes permissible and effective, even before performing ghusl (definition) (ritual bath) after menstruation. The default is that this divorce is valid, unless the husband pronounced the divorce while being overcome and not in control of his faculties, in which case his divorce would not be effective. It is advisable to present the matter to scholars in Islamic centers for further inquiry from the husband about his state at the time of uttering the divorce.
