How is the estate of a woman who died leaving two daughters, two paternal half-sisters, a paternal half-brother's son, and paternal half-sister's sons and daughters distributed?

The two daughters receive two-thirds as a prescribed share, and the two sisters receive the remaining third by virtue of 'asabah (agnatic succession). The issue is correctly calculated from six shares: the two daughters receive four shares, and the two sisters receive two shares. The brother's son and the sister's sons and daughters from the father receive nothing.
