Musnad Abu Ya'la al-Mawsili 115:192

Muhammad narrated to us, Abd al-Razzaq narrated to us, Ma'mar informed us, from Qatadah and Aban, from Anas: That the Messenger of Allah (peace be upon him) said to Ubayy ibn Ka'b, "My Lord commanded me to recite to you." He said, "And did He name me to you?" He said, "And He named you to me." He said, so Ubayy wept. Ma'mar said, Aban said, from Anas, and he mentioned [the rest of the hadith].
