Hadith 1150
This legal question was brought to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him): A deceased woman leaves behind a daughter, a granddaughter, and a full sister. He said: I will decide among them as the Prophet (peace and blessings of Allah be upon him) decided. The daughter will receive half, the granddaughter will receive one-sixth, and whatever remains will go to the sister.
