From Sahih Bukhari (Hadith 2390):
Narrated Abu Huraira:A man demanded his debts from Allah's Messenger (ﷺ) in such a rude manner that the companions of the Prophet intended to harm him, but the Prophet (ﷺ) said, "Leave him, no doubt, for he (the creditor) has the right to demand it (harshly). Buy a camel and give it to him." They said, "The camel that is available is older than the camel he demands. "The Prophet (ﷺ) said, "Buy it and give it to him, for the best among you are those who repay their debts handsomely
