"I was with the Prophet ﷺ on a journey, and he said: 'Stay back O Mughirah! Go ahead, O people!' So I went back, and I had with me a vessel of water. The people went ahead, and there the Messenger of Allah ﷺ relieved himself. when he came back I went and poured water for him. He was wearing a Roman Jubbah with narrow sleeves, and he wanted to expose his hands (to wash them) but the sleeves were too tight, so he brought his hands out from beneath the Jubbah and washed his head, and wiped over his Khuffs." (Using translation from Nasāʾī 125)  

كُنْتُ مَعَ رَسُولِ اللهِ ﷺ فِي سَفَرٍ فَقَالَ «تَخَلَّفْ يَا مُغِيرَةُ وَامْضُوا أَيُّهَا النَّاسُ فَتَخَلَّفْتُ وَمَعِي إِدَاوَةٌ مِنْ مَاءٍ وَمَضَى النَّاسُ فَذَهَبَ رَسُولُ اللهِ ﷺ لِحَاجَتِهِ فَلَمَّا رَجَعَ ذَهَبْتُ أَصُبُّ عَلَيْهِ وَعَلَيْهِ جُبَّةٌ رُومِيَّةٌ ضَيِّقَةُ الْكُمَّيْنِ فَأَرَادَ أَنْ يُخْرِجَ يَدَيْهِ مِنْهَا فَضَاقَتْ عَلَيْهِ فَأَخْرَجَ يَدَيْهِ مِنْ تَحْتِ الْجُبَّةِ» فَغَسَلَ وَجْهَهُ وَيَدَيْهِ وَمَسَحَ بِرَأْسِهِ وَمَسَحَ عَلَى خُفَّيْهِ
