Is the husband justified in obliging his wife to wear the niqab and not uncover her face in front of non-mahram men and her male relatives? What is the Sharia ruling on this, and what is the evidence for it? How should he act if his wife and their families reject his demands?

The disagreement regarding the obligation to cover the face and hands is well-known, but they agree on the obligation to cover the face of a woman who is feared to cause temptation. A wife must obey her husband in permissible matters, and controversial issues are more deserving of obedience if the husband commands one of the two views and his command is not forbidden. Jealousy over one's wife is praiseworthy, and the most important thing that helps with this is nurturing faith in her heart, educating her, and reminding her of Allah's promise and warning. Strangers should not be allowed to enter upon her, and the family should be informed of the legal ruling and the importance of virtue and chastity, as well as the dangers of ostentatious display (tabarruj) and mixing (ikhtilat). Scholars can be consulted for assistance in this regard.
