Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Imran bin Husain (may Allah be pleased with him) that a man came to the Holy Prophet (peace and blessings be upon him) and said, "My grandson has passed away, what will I receive from his inheritance?" The Prophet replied, "For you, there is one-sixth of the wealth." When he turned away, the Prophet called him back and said, "For you, there is another one-sixth." When he turned away again, the Prophet called him once more and said, "The second one-sixth is as a gift."
