Sayyiduna Imran bin Husayn (may Allah be pleased with him) narrates: Another man stood up and said: I bear witness that the Prophet (peace and blessings of Allah be upon him) gave the grandfather one-sixth. Sayyiduna Umar (may Allah be pleased with him) asked: With whom? He replied: I do not know. So Sayyiduna Umar (may Allah be pleased with him) said: You do not know either.
