Musannaf Ibn Abi Shaybah 1873 — Wiping over the leather socks

Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) said: I was with the Prophet (peace and blessings be upon him) on a journey. He went out to relieve himself. When he had finished, I brought him a vessel of water and poured it for him. He was wearing a cloak (jubbah) with narrow sleeves, so he brought his arms out from under the cloak, washed his forearms, and wiped over his leather socks.
