Amr bin Shu'aib narrates from his father, from his grandfather: The Prophet Muhammad (peace be upon him) said: "People belonging to different religions cannot inherit from one another." He also said: "A woman will inherit from her husband's blood money (diyah) and his wealth, and the man will inherit from this woman's blood money and her wealth. However, if one of them kills the other, then if he has intentionally killed his partner, he will not inherit from his wealth nor from the blood money. But if the deceased was killed by mistake, then (the other party) will inherit from his wealth, but will not inherit anything from the blood money."
