Narrated `Urwa bin Al-Mughira: My father said, "Once I was in the company of the Prophet on a journey and I dashed to take off his Khuffs (socks made from thick fabric or leather). He ordered me to leave them as he had put them after performing ablution. So he passed wet hands over them.

Narrated Ja`far bin `Amr bin Umaiya Ad-Damri: My father said, "I saw the Prophet passing wet hands over his Khuffs (socks made from thick fabric or leather)."

Narrated Al-Mughira: One night I was with the Prophet 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.
