6. A number of our people have narrated from Ahmad ibn Muhammad from Ahmad ibn Muhammad ibn abu Nasr who has said the following:

“I once asked abu al-Hassan, al-Rida , about wiping the backs of the feet as to how they must be wiped. He (the Imam) placed the palm of his hand over his toes add wiped to the ankles over the back of the feet. I then said, ’I pray to Allah to keep my soul in service for your cause, what happens if one places two fingers and wipes up to the ankle?’ He (the Imam) said, ‘No, it must be done with one’s palm.’”
