Mustadrak al-Hakim — Hadith 5273

It is narrated from Sayyiduna Ka'b bin Malik (may Allah be pleased with him) that Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) was a forbearing and generous young man, and he was among the best young men of his people. He would not keep anything back for himself, until he kept on borrowing and the burden of debt engulfed all his wealth. So he came to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) spoke to his creditors. If they had been willing to give up their right for anyone's sake, they would have let Mu'adh off his debt for the sake of the Messenger of Allah (peace and blessings be upon him). But (when they did not do so) the Messenger of Allah (peace and blessings be upon him) sold all his property and paid off his debt, until Mu'adh was left with nothing.
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
