“I once asked one of the two Imam, (abu Ja’far or abu ‘Abd Allah) (a.s.), about throwing pebbles on the day of al-Nahr (slaughtering the offering) and about why it is only one and why other al-Jamar are not pelted with pebbles on the day of al-Nahr. He (the Imam) said, ‘They used to throw pebbles on them but they stopped it.’ I then said, ‘I pray to Allah to keep my soul in service for your cause, can I then throw pebbles on them all?’ He (the Imam) said, ‘You must not throw pebbles on them all. Do you not like to do what we do?”’
