It was narrated that Huzail bin Shurahbil said: "A man came to Abu Musa AI-Ash' ari and Salman bin Rabi' ah Al-Bahili and asked them about (the shares of) a daughter, a son's daughter, a sister through one's father and mother. They said: 'The daughter gets one half, and what is left goes to the sister. Go to Ibn Mas'ud, for he will concur with what we say: So the man went to Ibn Mas'ud, and told him what they had said. 'Abdullah said: 'I will go astray and will not be guided (if I say that I agree); but I Will judge as the Messenger of Allah P.B.U.H judged. The daughter gets one half, and the son's daughter gets one-sixth. That makes two-thirds. And what is left goes to the sister:" (Sahih)
