Narrated `Abdullah bin Ka`b bin Malik from Ka`b bin Malik: `Abdullah bin Abu Hadrad Al-Aslami owed Ka`b bin Malik some money. One day the latter met the former and demanded his right, and their voices grew very loud. The Prophet passed by them and said, O Ka`b, beckoning with his hand as if intending to say, Deduct half the debts. So, Ka`b took half what the other owed him and remitted the other half.
