(27) CHAPTER. Washing both feet, and it is not sufficient to pass wet hands over the feet.
Narrated `Abdullah bin `Amr: The Prophet remained behind us on a journey. He joined us while we were performing ablution for the `Asr prayer which was overdue and we were just passing wet hands over our feet (not washing them thoroughly) so he addressed us in a loud voice saying twice , Save your heels from the fire.
