Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated Jabir (Radi-Allahu ‘anhu):
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.
