Muqatil bin Hayyan said: I came to Shahr bin Hawshab; he performed ablution and wiped over his leather socks. I said to him: Do you wipe over leather socks? He said: Jarir bin Abdullah (may Allah be pleased with him) came to me; he performed ablution and wiped over his leather socks. I said to him: Do you wipe over leather socks? He said: "Yes, I saw the Messenger of Allah (peace and blessings be upon him) wiping over his leather socks." I said: After the revelation of Surah al-Ma'idah? He said: "I accepted Islam after the revelation of Surah al-Ma'idah."
Abu Yuhmid said that Ibrahim bin Adham said: I have not heard any hadith about wiping over leather socks better than this one.
