Musannaf Ibn Abi Shaybah 1947 — Wiping over the leather socks

Abu Abd al-Rahman said: I was sitting with Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) when Sayyiduna Bilal (may Allah be pleased with him) passed by us. We asked him about wiping over leather socks, and he said: "After relieving himself, the Prophet (peace and blessings be upon him) would come out, and we would bring water to him. He would make ablution, then wipe over his leather socks and his turban."
