صحيح البخاري

Narrated Ka`b:

In the mosque l asked Ibn Abi Hadrad to pay the debts which he owed to me and our voices grew louder. Allah's Messenger (ﷺ) heard that while he was in his house. So he came to us raising the curtain of his room and said, "O Ka`b!" I replied, "Labaik, O Allah's Messenger!" He said, "O Ka`b! reduce your debt to one half," gesturing with his hand. I said, "O Allah's Messenger! I have done so." Then Allah's Apostle said (to Ibn Abi Hadrad), "Get up and pay the debt to him."
