Sahih Bukhari Volume 7, Book 72, Hadith Number 690.

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).
