Sahih al-Bukhari 43:9
Narrated Abu Huraira:
The Prophet (ﷺ) owed a camel of a certain age to a man who came to demand it back. The Prophet (ﷺ) ordered his companions to give him. They looked for a camel of the same age but found nothing but a camel one year older. The Prophet (ﷺ) told them to give it to him. The man said, "You have paid me in full, and may Allah pay you in full." The Prophet (ﷺ) said, "The best amongst you is he who pays his debts in the most handsome manner."

حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سُفْيَانُ، عَنْ سَلَمَةَ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ كَانَ لِرَجُلٍ عَلَى النَّبِيِّ صلى الله عليه وسلم سِنٌّ مِنَ الإِبِلِ فَجَاءَهُ يَتَقَاضَاهُ فَقَالَ صلى الله عليه وسلم " أَعْطُوهُ ". فَطَلَبُوا سِنَّهُ، فَلَمْ يَجِدُوا لَهُ إِلاَّ سِنًّا فَوْقَهَا. فَقَالَ " أَعْطُوهُ ". فَقَالَ أَوْفَيْتَنِي، وَفَّى اللَّهُ بِكَ. قَالَ النَّبِيُّ صلى الله عليه وسلم " إِنَّ خِيَارَكُمْ أَحْسَنُكُمْ قَضَاءً ".
