Is it permissible for a Muslim woman to remove her headscarf or face veil, or to wear a fashionable headscarf, after having committed to the correct head covering, as a means of forcing her husband not to marry another woman?

It is not permissible for a Muslim woman to remove her hijab or violate its conditions to prevent her husband from marrying another woman. Rather, she must be patient and seek reward, and not let jealousy push her to transgress the boundaries of Allah.
