Musnad Ahmad 30:3188

Isma'il narrated to us, he said: 'Abd al-Rahman ibn Ishaq informed us, from al-Zuhri, from Ibn Akimah al-Junda'i, from Abu Hurayrah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) performed a prayer in which he recited aloud. When he finished, he said: "Did any of you recite with me just now?" A man from the people said: "I did." He said: "I say, why am I being disputed with regarding the Qur'an?"
