It was narrated from Ibn 'Abbas: That during the time of the Messenger of Allah (ﷺ), a man pursued a debtor who owed him ten Dinar, and he said: “I do not have anything to give you.” He (the creditor) said: “No, by Allah, I will not leave you until you pay the debt or you bring me a guarantor.” Then he dragged him to the Prophet (ﷺ) and the Prophet (ﷺ) said to him: “How long will you wait?” He said: “One month.” The Messenger of Allah (ﷺ) said: “I will be a guarantor for him.” Then he came to him at the time the Prophet (ﷺ) had said, and the Prophet (ﷺ) said to him: “Where did you get this from?” He said: “From a mine.” He said: “There is nothing good in it,” and he paid the debt for him.
