Musnad Ahmad 1016:4

Ya'qub narrated to us, Ibn Akhi Ibn Shihab narrated to us, from his uncle, who said: Abd al-Rahman ibn Hurmuz informed me, from Abdullah ibn Buhaynah, and he was one of the companions of the Messenger of Allah, may Allah bless him and grant him peace, that the Messenger of Allah, may Allah bless him and grant him peace, said: "Did any of you recite with me just now?" They said: "Yes." He said: "I say, what is the matter with me that I am being disputed regarding the Quran?" So the people ceased reciting with him when he said that.
