Musnad Ahmad 26:600

Muhammad ibn Ja‘far narrated to us, Shu‘bah narrated to us, from al-Hakam, from Ibrahim, from ‘Abd al-Rahman ibn Yazid, that he performed Hajj with ‘Abdullah [ibn Mas‘ud]. He [‘Abdullah] threw seven pebbles at the Jamrah. He said: And he placed the House [the Ka‘bah] to his left and Mina to his right. And he said: "This is the station of the one upon whom Surah al-Baqarah was revealed."
