Musannaf Ibn Abi Shayba 1:1958

Abu Bakr narrated to us, he said: Abd al-Salam ibn Harb narrated to us, from Yazid al-Dalani, from Yahya ibn Ishaq ibn Abi Talha, from a man among the companions of the Prophet, may Allah bless him and grant him peace, regarding a man who wipes over his leather socks, then it occurs to him to remove his leather socks. He said: He washes his feet.
