Musannaf Ibn Abi Shaybah

Mansur narrates the statement of Ibrahim that the Noble Prophet, peace and blessings be upon him, divided one-sixth of the wealth between the maternal grandmother and the two paternal grandmothers. Hazrat Zaida says that I asked Hazrat Mansur, "By paternal grandmothers, do you mean the father's mother and the father's maternal grandmother?" He replied, "Yes!"
