Bismillah Walhamdulillah Was Salaatu Was Salaam 'ala Rasulillah

As-Salaam Alaikum Wa-Rahmatullahi Wa-Barakatuhu

I came to the Prophet (Sallallahu 'Alaihi Wa Sallam) in order to consult
him regarding my father's debt. When I knocked on the door, he asked, "Who is that?" I replied, "I" He said, "I, I?" He repeated it as if he disliked
it.

Note: the message here is that instead of saying "I" , tell your name
