On the Authority of ʿĀʾishah (رضي الله عنه) that some women from Ḥoms sought permission to enter upon her, and she replied: “Perhaps you are from those who enter the bathhouses. I heard the Messenger of Allāh (صلى الله عليه وسلم) say: ‘Any woman who removes her clothes in other than her husband’s house has torn the screen between her and Allāh'”. [Graded ṣaḥīḥ by al-Albānī in his ṣaḥīḥ of sunan ibn Mājah.]

Shaykh Muḥammad ibn Ṣāliḥ al-ʿUthaymīn comments: “If this Ḥadīth is authentic — that any woman who removes her clothes in other than her husband’s house has torn the screen—then it means that she removes her clothes in a situation where it is feared someone unlawful can enter upon her.”
