Sunan Ibn Majah Book 15, Hadith 35
the Prophet (ﷺ) borrowed thirty or forty thousand from him, when he fought at Hunain. When he came back he paid the loan, then the Prophet (ﷺ) said to him: 'May Allah (SWT) bless your family and your wealth for you. The reward for lending is repayment and words of paradise.”
“The best of you - or among the best of you - are those who pay off their debts in the best manner.”
“A man came to ask the Prophet of Allah (ﷺ) for some debt or some right, and he spoke harshly to him, and the Companions of the Messenger of Allah (ﷺ) wanted to rebuke him. But the Messenger of Allah (ﷺ) said: 'Let him be, for the one who is owed something has authority over the debtor, until it is paid off.' ”
