It was narrated from Al-Mughirah that the Prophet ﷺ performed Wudu', and he wiped the forehead, the 'Imamah, and over the Khuff. (Another chain) (Using translation from Nasāʾī 107)   

أَنَّ رَسُولَ اللهِ ﷺ «تَوَضَّأَ فَمَسَحَ نَاصِيَتَهُ وَعِمَامَتَهُ وَعَلَى الْخُفَّيْنِ» قَالَ بَكْرٌ وَقَدْ سَمِعْتُهُ مِنَ ابْنِ الْمُغِيرَةِ  

"The Messenger of Allah ﷺ stayed behind, and I stayed with him. When he had relieved himself he said: 'Do you have any water with you?' I brought some water to him, and he washed his hands and face, then he started trying to uncover his arms, but the sleeves of his Jubbah were too tight, so he threw it over his shoulders and washed his arms and wiped over his forehead and 'Imamah, and over his Khuff." (Using translation from Nasāʾī 108)   

تَخَلَّفَ رَسُولُ اللهِ ﷺ فَتَخَلَّفْتُ مَعَهُ فَلَمَّا قَضَى حَاجَتَهُ قَالَ «أَمَعَكَ مَاءٌ؟» فَأَتَيْتُهُ بِمِطْهَرَةٍ فَغَسَلَ يَدَهُ وَغَسَلَ وَجْهَهُ ثُمَّ ذَهَبَ يَحْسِرُ عَنْ ذِرَاعَيْهِ فَضَاقَ كُمُّ جُبَّتِهِ وَأَلْقَى الْجُبَّةَ عَلَى مَنْكِبَيْهِ فَغَسَلَ ذِرَاعَيْهِ وَمَسَحَ بِنَاصِيَتِهِ وَعَلَى الْعِمَامَةِ وَعَلَى خُفَّيْهِ قَالَ أَبُو عَبْدِ الرَّحْمَنِ وَقَدْ رَوَى هَذَا الْحَدِيثَ إِسْمَاعِيلُ بْنُ مُحَمَّدِ بْنِ سَعْدٍ عَنْ حَمْزَةَ بْنِ الْمُغِيرَةِ وَلَمْ يَذْكُرِ الْعِمَامَةَ  

"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 النَّبِيِّ 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»  

"We were with the Prophet ﷺ on a journey, and he tapped me on the back with a stick he had with him, then he turned off (route) and I turned off with him until he came to such and such an area. Then he made his camel stop and went away until he disappeared from me, then he came back and said: 'Do you have water with you?' I had a water skin with me, so I brought it out and poured it for him. He washed his hands and face and began to wash his arms, but he was wearing a Syrian Jubbah[1] that had narrow sleeves, so he brought his arms out from beneath the Jubbah and washed his hands and arms, and wiped his forelock a little and his turban a little." - Ibn 'Awn said: "I cannot remember it well - then he wiped over his Khuffs." Then he said: 'What do you need?' I said: 'O Messenger of Allah, I do not need anything.' Then we came and 'Abdur-Rahman bin 'Awf was leading the people in Salah, and he had led them in one Rak'ah of the Subh (Fajr) prayer. I wanted to tell him that the Prophet ﷺ had arrived but he did not let me, so we prayed what we had caught up with and made up what we had missed.'" [1] It is a type of cloak. (Using translation from Nasāʾī 82)  

كُنَّا مَعَ رَسُولِ اللهِ ﷺ فِي سَفَرٍ فَقَرَعَ ظَهْرِي بِعَصًا كَانَتْ مَعَهُ فَعَدَلَ وَعَدَلْتُ مَعَهُ حَتَّى أَتَيْنَا كَذَا وَكَذَا مِنَ الْأَرْضِ فَأَنَاخَ ثُمَّ انْطَلَقَ حَتَّى تَوَارَى عَنِّي ثُمَّ جَاءَ فَقَالَ «أَمَعَكَ مَاءٌ؟» وَمَعِي سَطِيحَةٌ لِي فَأَتَيْتُهُ بِهَا فَأَفْرَغْتُ عَلَيْهِ فَغَسَلَ يَدَيْهِ وَوَجْهَهُ وَذَهَبَ لِيَغْسِلَ ذِرَاعَيْهِ وَعَلَيْهِ جُبَّةٌ شَامِيَّةٌ ضَيِّقَةُ الْكُمَّيْنِ فَأَخْرَجَ يَدَيْهِ مِنْ تَحْتِ الثِّيَابِ فَغَسَلَ وَجْهَهُ وَذِرَاعَيْهِ وَذَكَرَ مِنْ نَاصِيَتِهِ شَيْئًا وَعِمَامَتِهِ فَقَالَ ابْنُ عَوْنٍ لَا أَحْفَظُ كَمَا أُرِيدُ ثُمَّ مَسَحَ عَلَى الْخُفَّيْنِ ثُمَّ قَالَ «حَاجَتُكَ؟» قُلْتُ يَا رَسُولَ اللهِ لَيْسَتْ لِي حَاجَةٌ فَجِئْنَا وَقَدْ أَمَّ النَّاسَ عَبْدُ الرَّحْمَنِ بْنِ عَوْفٍ وَقَدْ صَلَّى بِهِمْ رَكْعَةً مِنْ صَلَاةِ الصُّبْحِ فَذَهَبْتُ لِأُوذِنَهُ فَنَهَانِي فَصَلَّيْنَا مَا أَدْرَكْنَا وَقَضَيْنَا مَا سَبَقَنَا
