Book
of Ablution: Chapter: Passing wet hands over shoes covering ankles
Narrated
`Abdullaah bin `Umar: Sa`d bin Abi Waqqaas said, “The Prophet صلى الله عليه وسلم passed wet hands over his
Khuffs.” `Abdullaah bin `Umar asked `Umar
(ibn al-Khattaab) about it. `Umar replied in the affirmative and added,
"Whenever Sa'd narrates a Hadeeth from the Prophet صلى
الله عليه وسلم, there is no need to ask anyone else about it." [Saheeh
al-Bukhaaree (202)] [1]
