Jami` at-Tirmidhi 2093
Huzail bin Shurahbil said:
"A man came to Abu Musa and Salman bin Rabiah and asked them about a daughter, a son's daughter, a father's sister and a mother's sister. So they said: 'For the daughter is half, for the sister of the father  and the mother is what remains.' And they said to him: Go to Abdullah (bin Masud) and ask him, for surely he will concur with us.' So he went to  'Abdullah mentioning that to him and informing him what they had said. 'Abdulah said: 'If that were the case, then I would ave erred and not been among the rightly-guided (on the matter). Rather, I will judge with what the Messenger of Allah(S.A.W) judged: For the daughter is half, for the son's daughter a sixth, totaling two-thirds and for the sister is what remains.'"
