Sahih al-Bukhari, Volume 3, Book 41, Hadith 575 (USC-MSA) ⓘ

Narrated Abu Huraira: A man demanded his debts from Allah's Messenger in such a rude manner that the companions of the Prophet intended to harm him, but the Prophet said, "Leave him, no doubt, for he (the creditor) has the right to demand it (harshly). Buy a camel and give it to him." They said, "The camel that is available is older than the camel he demands. "The Prophet said, "Buy it and give it to him, for the best among you are those who repay their debts handsomely. "

حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا شُعْبَةُ، أَخْبَرَنَا سَلَمَةُ بْنُ كُهَيْلٍ، قَالَ سَمِعْتُ أَبَا سَلَمَةَ، بِبَيْتِنَا يُحَدِّثُ عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَجُلاً، تَقَاضَى رَسُولَ اللَّهِ صلى الله عليه وسلم، فَأَغْلَظَ لَهُ، فَهَمَّ أَصْحَابُهُ، فَقَالَ ‏"‏ دَعُوهُ، فَإِنَّ لِصَاحِبِ الْحَقِّ مَقَالاً‏.‏ وَاشْتَرُوا لَهُ بَعِيرًا، فَأَعْطُوهُ إِيَّاهُ ‏"‏‏.‏ وَقَالُوا لاَ نَجِدُ إِلاَّ أَفْضَلَ مِنْ سِنِّهِ‏.‏ قَالَ ‏"‏ اشْتَرُوهُ فَأَعْطُوهُ إِيَّاهُ، فَإِنَّ خَيْرَكُمْ أَحْسَنُكُمْ قَضَاءً ‏"‏‏.‏
