Asking, "Who is that?"

Narrated Jabir:

I came to the Prophet 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.

حَدَّثَنَا أَبُو الْوَلِيدِ، هِشَامُ بْنُ عَبْدِ الْمَلِكِ حَدَّثَنَا شُعْبَةُ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، قَالَ سَمِعْتُ جَابِرًا ـ رضى الله عنه ـ يَقُولُ أَتَيْتُ النَّبِيَّ ﷺ فِي دَيْنٍ كَانَ عَلَى أَبِي فَدَقَقْتُ الْبَابَ فَقَالَ " مَنْ ذَا ". فَقُلْتُ أَنَا. فَقَالَ " أَنَا أَنَا ". كَأَنَّهُ كَرِهَهَا.
