If a person dies, leaving a granddaughter (daughter of a son) and a great-grandson (son of a son of a son), how is the inheritance divided?

The estate of the deceased, who is survived by a son's daughter and a son's son's son, and leaves no other heirs, is divided into two shares: the son's daughter receives one-half share, and the son's son's son receives a share by 'asabah (agnatic inheritance). To divide the estate correctly, the heirs must be precisely and unambiguously identified. This can be done via the dedicated link provided for this purpose.
