صحيح البخاري

Narrated `Abdur-Rahman bin Yazid:

I performed Hajj with Ibn Mas`ud , and saw him doing Rami of the big Jamra (Jamrat-ul-Aqaba) with seven small pebbles, keeping the Ka`ba on his left side and Mina on his right. He then said, "This is the place where the one on whom Surat-al-Baqara was revealed (i.e. Allah's Messenger (ﷺ) ) stood."
