Inheritance of a woman's children with their maternal grandfather

Question:
If a woman dies and leaves behind sons and daughters, do they inherit together with their maternal grandfather or not? If a woman dies and leaves behind sons and daughters, do they inherit together with their maternal grandfather?

Answer:
If she leaves behind sons and daughters, and she leaves behind her father, who is her father and their grandfather, yes, it must be one of the causes. If a woman dies leaving her father and her children, her father gets one-sixth, and her mother gets one-sixth. If the grandfather is in that position, her grandfather gets one-sixth, if she has a father. If her father has died, her grandfather gets one-sixth, her father, or her father's father gets one-sixth. As for her mother's father, no, her mother's father has no share. As for her father, he gets one-sixth with her children, and her father's father, her grandfather, gets one-sixth with her children, and likewise her grandmother, her mother's mother or her father's mother, gets one-sixth with the children, and the rest goes to the children, the male getting the share of two females, as Allah the Exalted says: the females.
