"Perhaps you are among those (women) who enter bathhouses? I heard the Messenger of Allah ﷺ say: 'Any woman who takes off her clothes anywhere but in her husband's house, has torn the screen between her and Allah.'" (Using translation from Ibn Mājah 3750)
دَخَلَ عَلَى عَائِشَةَ نِسْوَةٌ مِنْ أَهْلِ حِمْصٍ يَسْتَفْتِينَهَا فَقَالَتْ لَعَلَّكُنَّ مِنَ النِّسْوَةِ اللَّاتِي يَدْخُلْنَ الْحَمَّامَاتِ؟ قُلْنَ نَعَمْ قَالَتْ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «مَا مِنَ امْرَأَةٍ تَضَعُ ثِيَابَهَا فِي غَيْرِ بَيْتِ زَوْجِهَا إِلَّا هَتَكَتْ مَا بَيْنَهَا وَبَيْنَ اللَّهِ ﷻ»
