Musnad Ahmad 312:2

Abu Nu'aym narrated to us, Sufyan narrated to us, from Zayd ibn Aslam, from Busr ibn Mihjan al-Dayli, from his father, who said: I came to the Prophet, peace and blessings of Allah be upon him, and I had already prayed with my family, and the prayer was then established. He then mentioned the meaning of the hadith of Abd al-Rahman.
