Musannaf Ibn Abi Shayba 3:1323

Yazid ibn Harun narrated to us, from Muhammad ibn ‘Amr, from Muhammad ibn Ibrahim, from ‘Abd al-Rahman ibn ‘Uthman, who said: I stood behind the Maqam (Station of Ibrahim) praying, and I intended that no one would overcome me for it that night. Then, a man nudged me from behind me, but I did not turn around. Then he nudged me again, so I turned around, and it was ‘Uthman ibn ‘Affan. So I moved aside, and he stepped forward and recited the [entire] Qur’an in one rak’ah, then he departed.
