Musannaf Ibn Abi Shaybah 1904 — Wiping over the leather socks

Sayyiduna Ibn Umar (may Allah be pleased with them both) said: At the time of the Battle of al-Qadisiyyah, Sayyiduna Sa'd (may Allah be pleased with him) and I differed about wiping over leather socks. He used to say: "Wipe over the leather socks," while I rejected it. When we came to Sayyiduna Umar (may Allah be pleased with him), Sayyiduna Sa'd mentioned the matter to him and said: "Ibn Umar (may Allah be pleased with them both) rejects wiping over leather socks." I said: "O Commander of the Believers! Sa'd says: Wipe over the leather socks after your ablution has been broken." Sayyiduna Umar said: "Wipe after your ablution has been broken, and wipe even after relieving yourself (defecating)."
