Lending to a person while knowing that the borrower will repay the loan with an increase

Question:
May Allah reward you with good. This questioner who sent this question via fax says: Honorable Shaykh Salih (may Allah preserve him), we love you for the sake of Allah and we make du'a for you. My question is that I lent a person a sum of money, knowing that it is his custom to repay more than what he borrowed from me. Does this count as a loan? Does it count as a loan that brought benefit?

Answer:
A loan that brings benefit, if you stipulated it from him, if you stipulated it from him, then it is of the loan that brought benefit. But if you did not stipulate it, but you know that he increases in the loan when repaying and he is good in settling the debt, then there is no harm in that. This is because the people used to lend to the Prophet (peace and blessings be upon him), and they knew that he (peace and blessings be upon him) was good in settling debts. Yes.
