Concept:Islamic law excludes a killer from inheriting the estate of the person he unlawfully killed.
Explanation:A person who murders his father in order to inherit his estate is barred from inheritance.
This is based on the principle that a killer cannot benefit from the death of the victim.
Such a person is excluded even though he would normally be an heir.
The rule applies to intentional homicide committed to gain the estate.
Brothers, husbands, and women are not excluded merely by these descriptions.
Only the murderer is disqualified from inheriting from the deceased.
