The Book of Purification (Kitab Al-Taharah)

Muslim :: Book 2 : Hadith 464

Salim, the freed slave of Shaddad, said: I came to 'A'isha, the wife of the Holy Prophet (may peace be upon him), on the day when Sa'db. Abi Waqqas died. 'Abd al-Rahman b. Abu Bakr also came there and he performed ablution in her presence. She (Hadrat 'A'isha) said: Abd al-Rahman, complete the ablution as I heard the Allah's Messenger (may peace be upon him) say: Woe to the heels because of hell-fire.
