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

“Abu al-Hassan , has said, ‘Pebbles for al-Jamar must be of the size of fingertips. You must not take the black ones, white ones, or red ones. Take those, which are like knickknack and dotted. You should hurl them by placing them on the thump and hurl them with the nail of your index finger. Throw them from the side of the valley when they are on your right side. You must not climb on al-Jamarah. You should stand near the two first al-Jamarah and do not stand near al-Jamarah al-‘Aqabah.’”
