Musnad Abu Ya'la al-Mawsili 149:70

'Abd al-A'la ibn Hammad al-Narsi narrated to us, Sufyan ibn 'Uyaynah narrated to us, from Ibn 'Ajlan, from Sa'id ibn Abi Sa'id, from Abu Salamah, who said: 'Abd al-Rahman performed ablution in the presence of 'Aishah. She said: "O 'Abd al-Rahman, perform the ablution thoroughly, for I heard the Messenger of Allah (may Allah bless him and grant him peace) saying: 'Woe to the heels from the Fire.'"
