What was the response of Prophet Muhammad (saw) when Ka'b bin Malik and Abdullah bin Abu Hadrad Al-Aslami were arguing over debt?
 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.
