Sahih al-Bukhari 2918
صحيح البخاري#2918SahihNarrated Al-Mughira bin Shu`ba:Allah's Messenger (ﷺ) went out to answer the call of nature and on his return I brought some water to him. He performed the ablution while he was wearing a Sha'mi cloak. He rinsed his mouth and washed his nose by putting water in it and then blowing it out, and washed his face. Then he tried to take out his hands through his sleeves but they were tight, so he took them out from underneath, washed them and passed wet hands over his head and over his leather socks
