Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: A man was owed a debt by the Prophet (peace and blessings be upon him), so he demanded it and spoke harshly. The Companions (may Allah be pleased with them) intended to punish him, but he (peace and blessings be upon him) said: "Leave him alone; indeed, the one who has a right to take is entitled to speak." Then he (peace and blessings be upon him) said: "Pay him." The Companions (may Allah be pleased with them) said: We have only a camel better than his camel. (He (peace and blessings be upon him) said:) "Buy it and give it to him; the best of you is the one who is best in repaying debts."
