From Sahih Bukhari (Hadith 2305):
Narrated Abu Huraira:The Prophet (ﷺ) owed somebody a camel of a certain age. When he came to demand it back, the Prophet (ﷺ) said (to some people), "Give him (his due)." When the people searched for a camel of that age, they found none, but found a camel one year older. The Prophet (ﷺ) said, "Give (it to) him." On that, the man remarked, "You have given me my right in full. May Allah give you in full." The Prophet (ﷺ) said, "The best amongst you is the one who pays the rights of others generously
