Ka'b bin Malik (may Allah be pleased with him) demanded his debt from Abdullah bin Abi Hadrad in the Prophet's Mosque, and their conversation became loud. So much so that the Messenger of Allah (peace and blessings of Allah be upon him) heard it from his chamber. He (peace be upon him) lifted the curtain and came out, and called: "O Ka'b!" Ka'b (may Allah be pleased with him) replied, "Yes, O Messenger of Allah! Please command, what do you order?" He (peace be upon him) said, "Reduce some of your debt." His (peace be upon him) gesture was that he should reduce it by half. He (Ka'b) said, "O Messenger of Allah! I have (willingly) done so." Then he (peace be upon him) said to Ibn Abi Hadrad, "Now get up and pay his debt (the half that has not been forgiven)."
