It is narrated from Sayyiduna Abu Rafi’ (may Allah be pleased with him), the freed slave of the Messenger of Allah (peace and blessings of Allah be upon him), that the Messenger of Allah (peace and blessings of Allah be upon him) took a camel on loan. Then, when camels from charity came to him, the Messenger of Allah (peace and blessings of Allah be upon him) ordered me to repay the debt of the person from whom the young camel had been taken. I said: I do not find among the camels anything except the best six-year-old camels. So the Messenger of Allah (peace and blessings of Allah be upon him) said:“Give him from those, for the best among people are those who are best in repaying debts.”

It is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) that a man came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! If I am killed in the way of Allah in such a state that I am patient, sincere in intention, advancing forward to attack and not turning my back, will Allah forgive my sins? The Messenger of Allah (peace and blessings be upon him) said: "Yes!" Then when that man turned and went back, the Messenger of Allah (peace and blessings be upon him) called him or ordered him to be called, then the Messenger of Allah (peace and blessings be upon him) said to him: "How did you say?" He repeated his statement, so the Prophet (peace and blessings be upon him) said to him: "Yes! Except for debt, thus Jibreel has told me."

And with this chain of narration (it is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him) that the Messenger of Allah, peace and blessings be upon him, said: "Delaying the repayment of a debt by a wealthy person is injustice, and if a debtor refers you to a wealthy person (saying that he will pay your debt), then you should accept it."
