Musannaf Ibn Abi Shaybah 34486 — Reports on Ubayy bin Kab

Ikrimah (may Allah have mercy on him) said that the Messenger of Allah (peace and blessings be upon him) said to Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him): "I have been commanded to teach you the Qur'an." He (may Allah be pleased with him) asked: "Did my Lord mention me?" He (peace and blessings be upon him) said: "Yes." He (may Allah be pleased with him) said: Whatever verse he (peace and blessings be upon him) taught me, I would repeat it before him (peace and blessings be upon him) a second time.
