If a father kills his son, does he inherit from him?

Question:
He says: Honorable Shaykh, may Allah grant you success, if a father kills his son, does he inherit from him?

Answer:
No, the killer does not inherit, whether he is the father, the son, or the brother. The killer does not inherit in any case. As I mentioned to you regarding the criterion: if the killing is guaranteed, meaning if the killing is guaranteed by retaliation, blood money, or expiation, then the killer does not inherit, whoever he is, whether father, son, brother, grandfather, and so on.
