Sunan Ibn Majah, Volume 5, Book 33, Hadith 3750 (DarusSalam) ⓘ

It was narrated from Abu Malih AL-HUdhail that some women from the people of Hims asked permission to enter upon Aisha. She said: "Perhaps you are among those (women) who enter bathhouses? I heard the Messenger of Allah say: 'Any woman who takes off her clothes anywhere but in her husband's house, has torn the screen between her and Allah.'"

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنْ سُفْيَانَ، عَنْ مَنْصُورٍ، عَنْ سَالِمِ بْنِ أَبِي الْجَعْدِ، عَنْ أَبِي الْمَلِيحِ الْهُذَلِيِّ، أَنَّ نِسْوَةً، مِنْ أَهْلِ حِمْصَ اسْتَأْذَنَّ عَلَى عَائِشَةَ فَقَالَتْ لَعَلَّكُنَّ مِنَ اللَّوَاتِي يَدْخُلْنَ الْحَمَّامَاتِ سَمِعْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ ‏ "‏ أَيُّمَا امْرَأَةٍ وَضَعَتْ ثِيَابَهَا فِي غَيْرِ بَيْتِ زَوْجِهَا فَقَدْ هَتَكَتْ سِتْرَ مَا بَيْنَهَا وَبَيْنَ اللَّهِ ‏" ‏ ‏.‏
