'Abd al-Razzaq narrated to us, Sufyan informed us, from al-A'mash, from Ibrahim, from 'Abd al-Rahman, who said: 'Abdullah used to stone the Jamrah from the valley floor. I said: "Do you stone it from here?" He said: "From here, by the One besides Whom there is no god, the one upon whom Surah al-Baqarah was revealed stoned it."
