How is the inheritance distributed among: a mother, two full sisters, two half-sisters (from the father's side), and two half-brothers (from the father's side)?

If the deceased's heirs are limited to those mentioned, the inheritance is divided as follows: The mother receives one-sixth (two shares out of twelve) due to the presence of siblings. The two maternal sisters receive one-third (four shares) due to their plurality. The remaining portion (six shares) goes to the paternal brothers by ta‘sib (agnatic succession), with the male receiving the equivalent of two females' shares. The original division is based on six, and it rectifies to twelve.
