Who are the heirs of the woman against whom a blood money payment of EGP 180,145 is due for premeditated murder, given that she is married, has one son, and has two parents and two grandparents, and how should the blood money be divided among them?

A mother who intentionally kills her child inherits nothing from the blood money (diyah) of the child, based on the Prophet's (PBUH) saying: "The killer inherits nothing."

If the infant has a father and two grandmothers (maternal grandmother and paternal grandmother), the maternal grandmother receives one-sixth, and the remainder goes to the father by virtue of 'asabah (agnatic relationship). So, the blood money is divided into six shares: one share for the grandmother and five for the father. The paternal grandfather and paternal grandmother inherit nothing because the father blocks them. The maternal grandfather is not an heir to begin with.

The maternal grandmother inherits and is not excluded by the mother, because the mother is excluded from inheritance due to being the killer. She does not, therefore, exclude others, according to the general consensus of scholars.
