They ask you for instruction. Say, "God instructs you concerning the indirect heirs. If a person dies childless but has a sister, she receives half of what he leaves, and he is her heir if she dies childless. If there are two sisters, they receive two-thirds of what he leaves. If there are brothers and sisters, the share of each male shall be that of two females. God makes things clear to you, so that you will not go astray. God has knowledge of all things."
