It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him), he says: The Messenger of Allah (peace and blessings be upon him) wiped over the leather socks (khuffs), this is correct, but ask those people whether the Noble Prophet (peace and blessings be upon him) wiped before the revelation of Surah Al-Ma'idah or after it. By Allah, he (peace and blessings be upon him) did not wipe after Surah Al-Ma'idah. I prefer, rather than wiping over the leather socks, to wipe my hand over the back of a traveler in the wilderness.
