Musannaf Ibn Abi Shaybah 1916 — Wiping over the leather socks

Iyad bin Nadlah said: We went with Sayyiduna Abu Musa (may Allah be pleased with him) into a garden. He went off to relieve himself, and so did I. When I came back, as soon as I began to take off my leather socks, he said: "Leave them, and wipe over them; when you are going to sleep, then take them off."
