Musannaf Ibn Abi Shaybah 1879 — Wiping over the leather socks

Ibn Buraydah narrates from his father (Sayyiduna Buraydah, may Allah be pleased with him) that the Negus (al-Najashi) sent the Prophet (peace and blessings be upon him) a gift of two plain black leather socks. He put them on, then performed ablution and wiped over them.
