Narrated 'Abdur-Rahman bin Yazid (Radi-Allahu 'anhu):
When 'Abdullah, reached the big Jamra (i.e. Jamrat-ul-Aqaba) he kept the
Ka'ba on the left side and Mina on his right side and threw seven pebbles
(at the Jamra) and said, "The one on whom Surat-al-Baqara was revealed
(i.e. the Prophet) had done the Rami similarly."
