Musnad Ahmad 26:144

Waki’ narrated to us, Sufyan narrated to us, from Abu Qays, from al-Huzayl ibn Shurahbil, who said: A man came to Abu Musa and Salman ibn Rabi’ah and asked them about a daughter, a son’s daughter, a sister from the father’s side, and a mother. They said: "For the daughter is half, and for the sister is half. Go to Ibn Mas’ud, for he will agree with us." He said: So he went to Ibn Mas’ud and asked him and informed him of what they had said. Ibn Mas’ud said: "I would have gone astray then, and I would not be among the guided. I will judge as the Messenger of Allah, peace and blessings of Allah be upon him, judged: For the daughter is half, and for the son’s daughter is one-sixth, to complete the two-thirds, and whatever remains is for the sister."
