Musnad Ahmad 30:715

Muhammad ibn Bakr narrated to us, Ibn Jurayj informed me, Ibn Shihab informed me, he said: I heard Ibn Akimah saying: Abu Hurayrah said: The Messenger of Allah (peace and blessings of Allah be upon him) led us in a prayer in which he recited aloud, then he performed the taslim, then he turned to the people and said: "Did anyone recite with me just now?" They said: Yes, O Messenger of Allah. He said: "I say, what is the matter with me that I am being disputed regarding the Qur'an?"
