How is the inheritance divided among two heirs (full paternal nephew) and two heiresses (full sister)?

If the deceased leaves no heirs other than two full sisters and two sons of a full brother, then the two full sisters inherit two-thirds by fard (prescribed share), in accordance with the Almighty's saying: ﴿But if there are two [sisters], they shall have two-thirds of what he left.﴾ The two sons of the full brother inherit the remainder by ta'sib (residuary inheritance), based on the Prophet's (peace and blessings be upon him) saying: «Give the prescribed shares to those entitled to them, and whatever remains is for the closest male relative.» Thus, the inheritance is divided into six shares: four shares for the two full sisters (two-thirds), and two shares for the two sons of the full brother (the remainder).
