Musannaf Ibn Abi Shayba 26:107

Hameed ibn Abd al-Rahman narrated to us, from Hasan ibn Salih, from Abd al-Aziz ibn Rufay, from Abu Burdah, that a man died and left behind his daughter and the freedmen who had emancipated him. The Prophet, peace and blessings of Allah be upon him, gave his daughter half and his freedmen half.
