Sahih Bukhari Volume 7, Book 77, Hadith 5800

حَدَّثَنَا قَيْسُ بْنُ حَفْصٍ، حَدَّثَنَا عَبْدُ الْوَاحِدِ، حَدَّثَنَا الأَعْمَشُ، قَالَ حَدَّثَنِي أَبُو الضُّحَى، قَالَ حَدَّثَنِي مَسْرُوقٌ، قَالَ حَدَّثَنِي الْمُغِيرَةُ بْنُ شُعْبَةَ، قَالَ انْطَلَقَ النَّبِيُّ صلى الله عليه وسلم لِحَاجَتِهِ ثُمَّ أَقْبَلَ، فَتَلَقَّيْتُهُ بِمَاءٍ، فَتَوَضَّأَ وَعَلَيْهِ جُبَّةٌ شَأْمِيَّةٌ، فَمَضْمَضَ وَاسْتَنْشَقَ وَغَسَلَ وَجْهَهُ، فَذَهَبَ يُخْرِجُ يَدَيْهِ مِنْ كُمَّيْهِ فَكَانَا ضَيِّقَيْنِ، فَأَخْرَجَ يَدَيْهِ مِنْ تَحْتِ الْجُبَّةِ، فَغَسَلَهُمَا وَمَسَحَ بِرَأْسِهِ وَعَلَى خُفَّيْهِ‏.‏

Narrated By Al-Mughira bin Shu'ba : The Prophet went to answer the call of nature, and when he returned, I met him with water and he performed the ablution while he was wearing a Sham, cloak. He rinsed his mouth, put the water in his nose and blew it out, washed his face and tried to take his hands out of his sleeves, but they were too narrow, so he took out his hands from under his chest and washed them and then passed his wet hands over his head and Khuffs (leather socks).
