The Prophet ﷺ owed me a debt, and he repaid it and gave me extra. This took place in the mosque, and he said to me, "Pray two rakahs."
حدثنا يحيى عن مسعر حدثني محارب قال سمعت
كان لي على النبي ﷺ دين فقضاني وزادني وكان في المسجد فقال لي صل ركعتين
Its isnad is sahih. Yahya is Ibn Saeed Ansari, Masaar is Ibn Kidam, and Muharib is Ibn Dithar. The hadith has been mentioned previously at 14169.
