Sahih al-Bukhari, Hadith 2394

Narrated Jabir bin `Abdullah: I went to the Prophet while he was in the Mosque. (Mas`ar thinks, that Jabir went in the forenoon.) After the Prophet told me to pray two rak`at, he repaid me the debt he owed me and gave me an extra amount.

حَدَّثَنَا خَلاَّدٌ، حَدَّثَنَا مِسْعَرٌ، حَدَّثَنَا مُحَارِبُ بْنُ دِثَارٍ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ قَالَ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم وَهْوَ فِي الْمَسْجِدِ ـ قَالَ مِسْعَرٌ أُرَاهُ قَالَ ضُحًى ـ فَقَالَ ‏ "‏ صَلِّ رَكْعَتَيْنِ ‏" ‏‏.‏ وَكَانَ لِي عَلَيْهِ دَيْنٌ فَقَضَانِي وَزَادَنِي‏.‏
