What is the share of three full sisters in the inheritance?

If the deceased leaves behind only three full sisters, they are entitled to two-thirds of the inheritance as a prescribed share (fard), based on Allah's saying: "And if there are two [sisters], they shall have two-thirds of what he leaves." They then receive the remaining one-third by way of return (radd), thus owning all the money equally. Cases of inheritance should be referred to the Sharia courts for investigation, as there may be wills, debts, or rights that take precedence over the heirs' entitlement.
