question #1 Sahih al-Bukhari 443, Book 8, Hadith 92 : What is the significance of performing two rak’ahs in the context of this event?

I went to the Prophet (ﷺ) in the mosque (the sub-narrator Mas`ar thought that Jabir had said, “In the
forenoon.”) He ordered me to pray two rak`at. He owed me some money and he repaid it to me and
gave more than what was due to me.
