Musannaf Ibn Abi Shayba 27:673

Abu Usama narrated to us, he said: Khalid bin Abi Karima narrated to me, from Sa'id, from Yasar al-Sadusi, from Ikrimah, he said: The Messenger of Allah (peace be upon him) said to Ubayy bin Ka'b: "I have been commanded to recite the Quran to you." He said: "And did my Lord mention me?" He said: "Yes." He said: "So he recited to me [a] verse, and I repeated it to him a second time."
