Does divorce or zihar occur if a husband, in a state of anger, says to his wife: "You are divorced if you do not remove your hijab in front of your sister's husband and put on full makeup," or "You are like my mother and sister"?

If you conditioned your wife's divorce on her removing her hijab, and your anger did not deprive you of your awareness, then if she does not remove it, the divorce occurs according to the majority of scholars. However, if she does what you intended, then no divorce occurs. You must know that a husband's command to his wife to display her adornments in front of her sister's husband is reprehensible both religiously and naturally, and it is not permissible for the wife to obey her husband in this, because he is a stranger [non-mahram]. You should avoid using words of divorce and prohibition as threats, and strive to overcome severe anger, for it is the root of all evil.
