Musnad Ahmad 626:26

'Abd al-Razzaq narrated to us, Sufyan informed us, from al-A'mash, from Abu al-Duha, from al-Mughirah ibn Shu'bah, who said: "I was with the Prophet, peace and blessings of Allah be upon him, on a journey. He relieved himself, then I brought him a vessel of water. He was wearing a Syrian cloak. He was unable to take his hands out from its sleeves, so he brought his hands out from beneath it. Then he performed ablution and wiped over his leather socks."
