Allah's Messenger (ﷺ) took a camel on loan, and then returned him (the lender) the camel of a more mature age and said: Good among you are those who are good in clearing off the debt.
Sahih Muslim Book 22, Hadith 150
← Previous Hadith Allah's Messenger (ﷺ) owed (something) to a person. He behaved in an uncivil manner with him. This vexed the Companions of the Prophet (ﷺ), whereupon Allah's Apostle (ﷺ) said: He who has a right is entitled to speak, and said to them (his Companions): Buy a camel for him and give that to him. They said: We do not find a camel (of that age) but one with better age than that. He said: Buy that and give that to him, for best of you or best amongst you are those who are best in paying off debt.

Sahih Muslim Book 22, Hadith 149 Next Hadith → There came a person demanding a camel from Allah's Messenger (ﷺ). He (the Holy Prophet) said: Give him (the camel) of that age or of more mature age, and said: Best among you is one who is best in clearing off the debt.
