How is the inheritance of a deceased woman divided, leaving behind: a mother, five full sisters, and three full paternal cousins?

If the deceased leaves behind only a mother, five full sisters, and three full paternal cousins, then the mother receives one-sixth due to the presence of a group of sisters. The full sisters receive two-thirds, and the remainder goes to the full paternal cousins by way of ta'sib (residuary heirship).

Thus, the inheritance is divided into ninety shares: the mother receives fifteen shares, the sisters receive sixty shares (twelve for each), and the full paternal cousins receive fifteen shares (five for each).
