Hammam bin Al-Harith said, "I saw Jarir bin ʿAbdullah urinating. Then he performed ablution and passed his (wet) hands over his Khuffs (socks made from thick fabric or leather), stood up and prayed. He was asked about it. He replied that he had seen the Prophet ﷺ doing the same." They approved of this narration as Jarir was one of those who embraced Islam very late.  

رَأَيْتُ جَرِيرَ بْنَ عَبْدِ اللَّهِ بَالَ ثُمَّ تَوَضَّأَ وَمَسَحَ عَلَى خُفَّيْهِ ثُمَّ قَامَ فَصَلَّى فَسُئِلَ فَقَالَ رَأَيْتُ النَّبِيَّ ﷺ صَنَعَ مِثْلَ هَذَا  

The Prophet ﷺ and I walked till we reached the dumps of some people. He stood, as any one of you stands, behind a wall and urinated. I went away, but he beckoned me to come. So I approached him and stood near his back till he finished.  

رَأَيْتُنِي أَنَا وَالنَّبِيُّ ﷺ نَتَمَاشَى فَأَتَى سُبَاطَةَ قَوْمٍ خَلْفَ حَائِطٍ فَقَامَ كَمَا يَقُومُ أَحَدُكُمْ فَبَالَ فَانْتَبَذْتُ مِنْهُ فَأَشَارَ إِلَىَّ فَجِئْتُهُ فَقُمْتُ عِنْدَ عَقِبِهِ حَتَّى فَرَغَ  

Once Messenger of Allah ﷺ went out to answer the call of nature and I followed him with a tumbler containing water, and when he finished, I poured water and he performed ablution and passed wet hands over his Khuffs (socks made from thick fabric or leather).  

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ خَرَجَ لِحَاجَتِهِ فَاتَّبَعَهُ الْمُغِيرَةُ بِإِدَاوَةٍ فِيهَا مَاءٌ فَصَبَّ عَلَيْهِ حِينَ فَرَغَ مِنْ حَاجَتِهِ فَتَوَضَّأَ وَمَسَحَ عَلَى الْخُفَّيْنِ  

Once I was traveling with the Prophet ﷺ and he said, "O Mughira! take this container of water." I took it and Messenger of Allah ﷺ went far away till he disappeared. He answered the call of nature and was wearing a Syrian cloak. He tried to take out his hands from its sleeve but it was very tight so he took out his hands from under it. I poured water and he performed ablution like that for prayers and passed his wet hands over his Khuff (socks made from thick fabric or leather) and then prayed .  

كُنْتُ مَعَ النَّبِيِّ ﷺ فِي سَفَرٍ فَقَالَ يَا مُغِيرَةُ خُذِ الإِدَاوَةَ فَأَخَذْتُهَا فَانْطَلَقَ رَسُولُ اللَّهِ ﷺ حَتَّى تَوَارَى عَنِّي فَقَضَى حَاجَتَهُ وَعَلَيْهِ جُبَّةٌ شَأْمِيَّةٌ فَذَهَبَ لِيُخْرِجَ يَدَهُ مِنْ كُمِّهَا فَضَاقَتْ فَأَخْرَجَ يَدَهُ مِنْ أَسْفَلِهَا فَصَبَبْتُ عَلَيْهِ فَتَوَضَّأَ وُضُوءَهُ لِلصَّلاَةِ وَمَسَحَ عَلَى خُفَّيْهِ ثُمَّ صَلَّى  

One night I was with the Prophet ﷺ on a journey. He asked (me), "Have you got water with you?" I replied, "Yes" So he got down from his she-camel and went away till he disappeared in the darkness of the night. Then he came back and I poured water for him from the pot (for the ablution). He washed his face and hands while he was wearing a woollen cloak (the sleeves of which were narrow), so he could not take his arms out of it. So he took them out from underneath the cloak. Then he washed his forearms and passed his wet hands over his head. Then I tried to take off his Khuffs (socks made from thick fabric or leather), but he said, "Leave them, for I have performed ablution before putting them on." And so he passed his wet hands over them.  

كُنْتُ مَعَ النَّبِيِّ ﷺ ذَاتَ لَيْلَةٍ فِي سَفَرٍ فَقَالَ أَمَعَكَ مَاءٌ قُلْتُ نَعَمْ فَنَزَلَ عَنْ رَاحِلَتِهِ فَمَشَى حَتَّى تَوَارَى عَنِّي فِي سَوَادِ اللَّيْلِ ثُمَّ جَاءَ فَأَفْرَغْتُ عَلَيْهِ الإِدَاوَةَ فَغَسَلَ وَجْهَهُ وَيَدَيْهِ وَعَلَيْهِ جُبَّةٌ مِنْ صُوفٍ فَلَمْ يَسْتَطِعْ أَنْ يُخْرِجَ ذِرَاعَيْهِ مِنْهَا حَتَّى أَخْرَجَهُمَا مِنْ أَسْفَلِ الْجُبَّةِ فَغَسَلَ ذِرَاعَيْهِ ثُمَّ مَسَحَ بِرَأْسِهِ ثُمَّ أَهْوَيْتُ لأَنْزِعَ خُفَّيْهِ فَقَالَ دَعْهُمَا فَإِنِّي أَدْخَلْتُهُمَا طَاهِرَتَيْنِ فَمَسَحَ عَلَيْهِمَا
