How is the inheritance divided among the wife, three paternal half-brothers, seven paternal half-sisters, and one maternal half-sister?

If the deceased's heirs are limited to those mentioned, then his estate is divided as follows: The wife receives one-fourth as a prescribed share due to the absence of a descendant heir. The sister from the mother's side receives one-sixth for being a sole heir. What remains after the prescribed shares of the wife and the sister from the mother's side goes to the brothers and sisters from the father's side by virtue of 'asaba (agnatic succession), divided among them with the male receiving the share of two females. The original basis of the estate is 12 and it is corrected to 156. The wife receives 39, the sister from the mother's side receives 26, and the remainder goes to the brothers and sisters from the father's side; thus, each sister receives 7 shares and each brother receives 14 shares.
