Musnad Ahmad 32:463

'Abd al-Razzaq narrated to us, Ma'mar informed us, from Qatadah, from Anas, from the Prophet, peace and blessings of Allah be upon him, that he said to Ubayy ibn Ka'b: "My Lord commanded me to recite the Qur'an to you." Ubayy said: "Did He name me to you?" He said: "Yes." So Ubayy wept.
