What is the meaning of the noble Hadith which states that a woman who removes her clothes outside her husband's house has committed a grave matter? And how does she sin by doing so if she does it in a closed room? And does this include the restroom or her father's house? And what if she is compelled to do so?

The Hadith about a woman taking off her clothes outside her husband's home is authentic, and its wording is: "Any woman who takes off her clothes in other than her husband's house has torn the veil between her and Allah." Its apparent meaning is that taking off clothes implies uncovering oneself before a non-mahram, unlike if she takes off her clothes among women while maintaining the covering of her awrah. Accordingly, taking off clothes in a private room or in a restroom is not forbidden, and the same applies if she is with other women or her mahram men and limits herself to showing only what she is permitted to show.
