Saeed bin Musayyib narrates that the Noble Prophet (peace and blessings be upon him) gave this ruling: Whoever kills someone, whether intentionally or by mistake, will not inherit the blood money (diyah) of the slain person. And Zuhri says: The killer will not inherit anything from the slain person, whether he is his son or his father. However, he will inherit from the slain person’s own wealth, because Allah Almighty knows that people will kill one another, and no one has the right to abolish those inheritances which Allah Almighty has prescribed.
