I heard Abu Umamah Al-Bahil say: “I heard the Messenger of Allah(ﷺ) say: “The guarantor is responsible and the debt must be repaid.' ”
Sunan Ibn Majah Book 15, Hadith 16
← Previous Hadith “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.”

Sunan Ibn Majah Book 15, Hadith 15 Next Hadith → 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.
