Musnad Ahmad 30:698

'Abd al-Razzaq narrated to us, Ma'mar narrated to us, from Muhammad ibn Ziyad, who said: I saw Abu Hurayrah pass by some people who were performing ablution from a water container. He said: "Perform the ablution well, may Allah have mercy on you. Have you not heard what the Messenger of Allah, peace and blessings of Allah be upon him, said: 'Woe to the heels from the Fire.'"
