Musannaf Ibn Abi Shaybah 1963 — Those who did not accept wiping

Isma'il bin Salim said: Mujahid and some of his companions, among them Abdah bin Abi Lubabah, were travelling with the intention of Hajj. Abdah used to lead them in prayer. One day he went out to relieve himself and took a long time. When he came back, Mujahid said to him: "Why were you late?" He said: "I relieved myself, then I performed ablution and wiped over my khuffs (leather socks)." Mujahid said: "Go forward and lead us in prayer; I do not know what suffices for your prayer (washing or wiping?)."
