Musannaf Ibn Abi Shaybah 1949 — Wiping over the leather socks

Nusayr said: Once Sayyiduna Sa'd bin Malik (may Allah be pleased with him) wiped over his leather socks, and Sayyiduna Ibn Umar (may Allah be pleased with them both) objected to it. He mentioned this to his father, who said: "Sa'd bin Malik knows more than you."
