from Laith, from Nafi, from Ibn 'Umar that the Messenger of Allah ﷺ said: "Beware of nakedness! For indeed there are with you, those who do not part from you except at the place of defecation, and when a man goes into his wife. So be shy of them and honor them."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِيَّاكُمْ وَالتَّعَرِّي فَإِنَّ مَعَكُمْ مَنْ لاَ يُفَارِقُكُمْ إِلاَّ عِنْدَ الْغَائِطِ وَحِينَ يُفْضِي الرَّجُلُ إِلَى أَهْلِهِ فَاسْتَحْيُوهُمْ وَأَكْرِمُوهُمْ
