What was narrated about being concealed when bathing

Abu Samh said:
"I used to serve the Prophet, and when he wanted to take a bath he would say: 'Turn your back to me.' So I would turn my back and hung up a cloth, and concealed him with it."

حَدَّثَنَا الْعَبَّاسُ بْنُ عَبْدِ الْعَظِيمِ الْعَنْبَرِيُّ، وَأَبُو حَفْصٍ عَمْرُو بْنُ عَلِيٍّ الْفَلاَّسُ وَمُجَاهِدُ بْنُ مُوسَى قَالُوا حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا يَحْيَى بْنُ الْوَلِيدِ، أَخْبَرَنِي مُحِلُّ بْنُ خَلِيفَةَ، حَدَّثَنِي أَبُو السَّمْحِ، قَالَ كُنْتُ أَخْدُمُ النَّبِيَّ ﷺ فَكَانَ إِذَا أَرَادَ أَنْ يَغْتَسِلَ قَالَ " وَلِّنِي " . فَأُوَلِّيهِ قَفَاىَ وَأَنْشُرُ الثَّوْبَ فَأَسْتُرُهُ بِهِ .

It was narrated that 'Abdullah bin Harith bin Nawfal said:
"I asked whether the Messenger of Allah prayed voluntary prayer when traveling, but I could not find anyone to tell me until Umm Hani' bint Abu Talib told me that he had come during the year of the Conquest (of Makkah). He ordered that a screen be held up, and that was done, and he took a bath; then he prayed eight Rak'ah (units) of voluntary prayer."

حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ الْمِصْرِيُّ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ نَوْفَلٍ، أَنَّهُ قَالَ سَأَلْتُ فَلَمْ أَجِدْ أَحَدًا يُخْبِرُنِي أَنَّ رَسُولَ اللَّهِ ﷺ سَبَّحَ فِي سَفَرٍ حَتَّى أَخْبَرَتْنِي أُمُّ هَانِئٍ بِنْتُ أَبِي طَالِبٍ أَنَّهُ قَدِمَ عَامَ الْفَتْحِ فَأَمَرَ بِسِتْرٍ فَسُتِرَ عَلَيْهِ فَاغْتَسَلَ ثُمَّ سَبَّحَ ثَمَانِيَ رَكَعَاتٍ .
