Narrated Abu Huraira:
The Prophet owed a camel of a certain age to a man who came to demand it back. The Prophet 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 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 said, "The best amongst you is he who pays his debts in the most handsome manner."
