[Nisa 4:176] O dear Prophet (Mohammed - peace and blessings be upon him), they ask you for a decree; say, "Allah decrees you concerning the solitary person (without parents or children); if a man dies childless and has a sister, for her is half the inheritance; and the man is his sisterís heir if the sister dies childless; and if there are two sisters, for them is two-thirds of the inheritance; so if there are brothers and sisters, both men and women, the maleís share is equal to that of two females; and Allah explains clearly to you, so that you do not go astray; and Allah knows all things."
