The Book of Pilgrimage (Kitab Al-Hajj)
Muslim :: Book 7 : Hadith 2973
Abd al-Rahman b. Yazid reported that he performed Hajj along with 'Abdullah (Allah be pleased with him) and he flung seven pebbles at al-Jamra (from a position) that the House was on his left and Mina was on his right and said: That is the place (of flinging pebbles of one) upon whom Surah al-Baqara was revealed.
