سنن النسائي

It was narrated from 'Abdullah bin Ka'b, from his father, that : He asked Ibn Abi Hadrad to pay off a debt that he owed him. Their voices grew so loud that the Messenger of Allah (ﷺ) [SAW] heard them when he was inside his house. He came out to them, drew back the curtain of his room and called out: "O Ka'b!" He said: "Here I am, O Messenger of Allah." He said: "Drop his debt to half." He said: "I will do that." He said (to the debtor): "Go and pay it off."
