Musnad Ahmad 33:792

'Affan narrated to us, Shu'bah narrated to us, Muhammad ibn al-Munkadir informed me, from Jabir ibn 'Abdullah, who said: I came to the Prophet, peace and blessings of Allah be upon him, and I knocked on the door. He said, "Who is this?" I said, "I." He said, "I, I," as if he disliked it.
