They ask thee for a decision. Say: Allah gives you a decision concerning the person who has neither parents nor children. If a man dies (and) he has no son and he has a sister, hers is half of what he leaves, and he shall be her heir if she has no son. But if there be two (sisters), they shall have two-thirds of what he leaves. And if there are brethren, men and women, then for the male is the like of the portion of two females. Allah makes clear to you, lest you err. And Allah is Knower of all things.
