Musnad Abu Ya'la al-Mawsili 151:6

Abu Khaythama narrated to us, Hushaym ibn Bashir narrated to us, Mughira narrated to us, from Ibrahim, from Abd al-Rahman ibn Yazid, who said: I saw Abdullah ibn Mas'ud stone the Jamrat al-Aqaba from the bottom of the valley. He said: "This—by the One besides whom there is no god—is the standing place of the one upon whom Surat al-Baqarah was revealed."
