"Go and buy a young camel for him." He came and said: "I could only get a Raba camel of good quality." He said: "Give it to him, for the best of the Muslims is the one who is best in repaying." (Using translation from Nasāʾī 4617)  

أَنَّ رَسُولَ اللهِ ﷺ اسْتَسْلَفَ مِنْ رَجُلٍ بَكْرًا فَأَتَاهُ الرَّجُلُ يَتَقَاضَاهُ بَكْرَهُ فَقَالَ لِرَجُلٍ «انْطَلِقْ فَابْتَعْ لَهُ بَكْرًا» فَأَتَاهُ فَقَالَ مَا أَصَبْتُ إِلَّا بَكْرًا رَبَاعِيًا خِيَارًا قَالَ «أَعْطِهِ فَإِنَّ خَيْرَ الْمُسْلِمِينَ أَحْسَنُهُمْ قَضَاءً»  

"A man had lent a camel of a certain age to the Prophet and he came to get it back. He said: "Give it to him" But they could only find a camel that was older than it. He said: "Give it to him." He said: "You have repaid me well," The Messenger of Allah said; "The best of you is the one who is best in repaying" (Using translation from Nasāʾī 4618)  

كَانَ لِرَجُلٍ عَلَى النَّبِيِّ ﷺ سِنٌّ مِنَ الْإِبِلِ فَجَاءَ يَتَقَاضَاهُ فَقَالَ «أَعْطُوهُ» فَلَمْ يَجِدُوا لَهُ إِلَّا سِنًّا فَوْقَ سِنِّهِ قَالَ «أَعْطُوهُ» فَقَالَ أَوْفَيْتَنِي فَقَالَ رَسُولُ اللهِ ﷺ «إِنَّ خِيَارَكُمْ أَحْسَنُكُمْ قَضَاءً»  

"I lent a young camel to the Messenger of Allah, and I came to ask him to repay me. He said: 'Yes, I will only repay you with a superior she-camel.' so he repaid me and repaid me well. Then a Bedouin came to him to ask to repay him a camel of a certain age, and the Messenger of Allah said: 'Give him a camel of certain age.' On that day they gave him a mature camel and he said: 'This is better than my camel.' He (The Prophet) Said:' The best of you is the one who is best in repaying.''' (Using translation from Nasāʾī 4619)  

سَمِعْتُ عِرْبَاضَ بْنَ سَارِيَةَ يَقُولُ بِعْتُ مِنَ النَّبِيِّ ﷺ بَكْرًا فَأَتَيْتُهُ أَتَقَاضَاهُ فَقَالَ «أَجَلْ لَا أَقْضِينَّكَهَا إِلَّا لُجَيْنِيَّةً» فَقَضَانِي فَأَحْسَنَ قَضَائِي وَجَاءَهُ أَعْرَابِيٌّ يَتَقَاضَاهُ سِنَّهُ فَقَالَ رَسُولُ اللهِ ﷺ «أَعْطُوهُ سِنًّا» فَأَعْطُوهُ يَوْمَئِذٍ جَمَلًا فَقَالَ هَذَا خَيْرٌ مِنْ سِنِّي فَقَالَ «خَيْرُكُمْ خَيْرُكُمْ قَضَاءً»
