Sunan Ibn Majah Book 15, Hadith 14
“(Wrongdoing) is when a rich man takes a long time to repay a debt, and if one of you is referred to a rich man (to collect a debt), he should accept that referral.”
the Prophet (ﷺ) gave him a Dinar to buy him a sheep, and he bought two sheep for him, then he sold one of them for a Dinar, and bought a Dinar and a sheep to the Prophet (ﷺ). The Messenger of Allah (ﷺ) prayed for blessing for him.
“When a rich man takes too long to repay a debt, this is wrongdoing, and if the debt is transferred to a rich man, you should accept if.”
