"I used to serve the Messenger of Allah ﷺ and when he wanted to perform Ghusl he said: 'Turn your back.' So I turned my back to him and concealed him." (Using translation from Nasāʾī 224)  

كُنْتُ أَخْدُمُ النَّبِيَّ ﷺ فَكَانَ إِذَا أَرَادَ أَنْ يَغْتَسِلَ قَالَ «وَلِّنِي قَفَاكَ فَأُوَلِّيهِ قَفَايَ فَأَسْتُرُهُ بِهِ»  

"Who is this?" She said: "Umm Hani'." When he had finished his Ghusl he stood up and prayed eight Rak'ahs wrapped in a garment. (Using translation from Nasāʾī 225)  

أَنَّهَا ذَهَبَتْ إِلَى النَّبِيِّ ﷺ يَوْمَ الْفَتْحِ فَوَجَدْتُهُ يَغْتَسِلُ وَفَاطِمَةُ تَسْتُرُهُ بِثَوْبٍ فَسَلَّمْتُ فَقَالَ «مَنْ هَذَا؟» قُلْتُ أُمُّ هَانِئٍ فَلَمَّا فَرَغَ مِنْ غُسْلِهِ قَامَ فَصَلَّى ثَمَانِيَ رَكَعَاتٍ فِي ثَوْبٍ مُلْتَحِفًا بِهِ
