Hadith 2666
Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) said: I came to the Messenger of Allah (peace and blessings be upon him) and knocked at his door. The Messenger of Allah (peace and blessings be upon him) said: "Who is it?" I said: "It is I." He (peace and blessings be upon him) said: "'It is I,' 'It is I,'" as if he disliked it.
