Abu Huraira reported the Prophet as saying, “If anyone accepts other people’s belongings meaning to pay back, God will pay back for him; but if anyone accepts them meaning to squander them, God will on that account destroy his property.”
While we were sitting with the Prophet a bier was brought along and the Prophet was asked to pray over it. He asked whether the dead man owed anything and when he was told that he did not he prayed over it. Another bier was brought along later, and when he asked whether the dead man owed anything and was told that he did, he asked whether he had left anything. On being told that he had left three dinars he prayed over the bier. A third was brought along later, and when he asked whether the dead man owed anything and was told that he owed three dinars, he asked whether he had left anything. On being told that he had not, he ordered them to pray over their friend; but when Abu Qatada said, “Pray over him, Messenger of God, and I shall be responsible for his debt,” he prayed over him.
Abu Qatada told of a man saying, “Tell me, Messenger of God, if I am killed in God’s path showing endurance, seeking my reward from God, advancing and not retreating, will God efface my sins?” He replied, “Yes,” but when the man turned away he called him and said, “Yes, with the exception of a debt. Thus Gabriel said.”
Ka'b b. Malik said that in the time of God’s Messenger he made demand in the mosque for payment of a debt due to him from Ibn Abu Hadrad and their voices rose till God’s Messenger, who was in his house, heard them. He went out to them and removing the curtain of his chamber called to Ka'b b. Malik addressing him by name. He replied, “At your service, Messenger of God", whereupon he made a gesture with his hand indicating that he should remit half the debt due to him, and when Ka'b expressed his willingness he told the other to get up and discharge his debt.
