Mishkat al-Masabih 11 Business Transactions كتاب البيوع 143

وَعَنْ أَبِي هُرَيْرَةَ أَنَّ رَجُلًا تَقَاضَى رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَغْلَظَ لَهُ فَهَمَّ أَصْحَابُهُ فَقَالَ: «دَعُوهُ فَإِنَّ لِصَاحِبِ الْحَقِّ مَقَالًا وَاشْتَرُوا لَهُ بَعِيرًا فَأَعْطُوهُ إِيَّاهُ» قَالُوا: لَا نَجِدُ إِلَّا أَفْضَلَ مِنْ سِنِّهِ قَالَ: «اشْتَرُوهُ فَأَعْطُوهُ إِيَّاهُ فَإِنَّ خَيْرَكُمْ أحسنكم قَضَاء»

Abu Huraira told that a man demanded payment of a debt from God’s Messenger in a most uncivil manner and his companions were vexed, but he said, “Leave him alone, for one who has a right is entitled to speak, and buy him a camel and give it to him.” When they told him that all they could find was one of a more excellent age than the man was entitled to, he said, “Buy it and give him it, for the best person among you is he who discharges his debt in the best manner.” (Bukhari and Muslim.)
