They ask you (O Messenger) to pronounce a ruling. Say (to them): God pronounces to you the ruling concerning inheritance from those who have left behind no lineal heirs (kalalah): should a man die childless but have a sister, for her is the half of what he has left behind; and the brother will inherit from her if the sister dies childless. If the heirs are two sisters, for them is two-thirds of what he has left behind. And if the heirs are brothers and sisters, then for the male is the equivalent of the portion of two females. God makes (His commandments) clear to you lest you go astray. God has full knowledge of everything.
