Sahih al-Bukhari 2609
Narrated Abu Huraira:
The Prophet (ﷺ) took a camel of special age from somebody on credit. Its owner came and demanded it 
back (harshly). The Prophet (ﷺ) said, "No doubt, he who has a right, can demand it." Then the Prophet (ﷺ) 
gave him an older camel than his camel and said, "The best amongst you is he who repays his debts in 
the most handsome way."
حَدَّثَنَا ابْنُ مُقَاتِلٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا شُعْبَةُ، عَنْ سَلَمَةَ بْنِ كُهَيْلٍ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ أَخَذَ سِنًّا فَجَاءَ صَاحِبُهُ يَتَقَاضَاهُ فَقَالَ ‏"‏ إِنَّ لِصَاحِبِ الْحَقِّ مَقَالاً ‏"‏‏.‏ ثُمَّ قَضَاهُ أَفْضَلَ مِنْ سِنِّهِ وَقَالَ ‏"‏ أَفْضَلُكُمْ أَحْسَنُكُمْ قَضَاءً ‏"‏‏.‏
