Sunan Ibn Majah Book 15, Hadith 39
“I came to the Prophet (ﷺ) with a man who owed me money, and he said to me: 'Keep him.' Then he passed by me at the end of the day and said: 'What did your prisoner do, O brother of Banu Tamim?' ”
“If one who can afford it delays repayment, his honor and punishment become permissible.”
he demanded payment owed by Ibn Abi Hadrad in the mosque. Their voices became so loud that the Messenger of Allah (ﷺ) heard them when he was in his house. He came out and called Ka'b who said: “Here I am, O Messenger of Allah (ﷺ)!” He said: “Waive this much of your loan,” and gestured with his hand to indicate half. He said: “I will do that,” and he said: “Get up and repay it.”
