Jabir (may Allah be pleased with him) reports: I came to the Prophet (peace and blessings of Allah be upon him) regarding the debt owed by my father, and I knocked at the door. The Prophet (peace and blessings of Allah be upon him) said: "Who is it?" I replied: "It is I." The Prophet (peace and blessings of Allah be upon him) said: "'It is I, it is I.'" As if he disliked this. Agreed upon.
