Sayyiduna Imran bin Husayn (may Allah be pleased with him) said: A man freed his six slaves at the time of his death, and the Prophet (peace and blessings be upon him) came concerning their matter. "He (peace and blessings be upon him) cast lots between them and the lot fell on two of them, so the Messenger of Allah (peace and blessings be upon him) freed the two on whom the lot fell and kept four in slavery."
