Sahih Muslim 1600 a
Abu Rafi' reported that Allah's Messenger (ﷺ) took from a man as a loan a young camel (below six years). Then the camels of Sadaqa were brought to him. He ordered Abu Rafi' to return to that person the young camel (as a return of the loan). Abu Rafi' returned to him and said:
I did not find among them but better camels above the age of six. He (the Holy Prophet) said: Give that to him for the best men are those who are best in paying off the debt.
حَدَّثَنَا أَبُو الطَّاهِرِ، أَحْمَدُ بْنُ عَمْرِو بْنِ سَرْحٍ أَخْبَرَنَا ابْنُ وَهْبٍ، عَنْ مَالِكِ بْنِ، أَنَسٍ عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي رَافِعٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم اسْتَسْلَفَ مِنْ رَجُلٍ بَكْرًا فَقَدِمَتْ عَلَيْهِ إِبِلٌ مِنْ إِبِلِ الصَّدَقَةِ فَأَمَرَ أَبَا رَافِعٍ أَنْ يَقْضِيَ الرَّجُلَ بَكْرَهُ فَرَجَعَ إِلَيْهِ أَبُو رَافِعٍ فَقَالَ لَمْ أَجِدْ فِيهَا إِلاَّ خِيَارًا رَبَاعِيًا ‏.‏ فَقَالَ ‏
"‏ أَعْطِهِ إِيَّاهُ إِنَّ خِيَارَ النَّاسِ أَحْسَنُهُمْ قَضَاءً ‏"‏ ‏.‏
