Abd al-Rahman bin Ka'b bin Malik narrates from his father (Sayyiduna Ka'b bin Malik, may Allah be pleased with him) that Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) was the most honoured and gentle young man of his people. He would not keep anything with himself, so he was always in debt, until all his property went into debt. He came to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) spoke to them (his creditors). If they had forgiven anyone a debt for someone's sake, they would have forgiven Mu'adh (may Allah be pleased with him) for the sake of the Messenger of Allah (peace and blessings be upon him). He (peace and blessings be upon him) sold the property of Sayyiduna Mu'adh (may Allah be pleased with him), and nothing remained with Mu'adh (may Allah be pleased with him).
