Who inherits from a deceased woman who has three sisters, three nephews (brother's sons), and three nieces (brother's daughters), and what is the share of each heir?

If the heirs are limited to those mentioned, then the two full sisters receive two-thirds, and the remainder goes to the male nephews by ta’sib (agnatic inheritance). The estate is divided into nine shares: the two sisters receive four shares (two shares for each sister), and the male nephews receive five shares (one share for each nephew). The nieces do not inherit. The questioner is advised to present the case to the Sharia courts to verify the absence of wills, debts, or other rights that take precedence over the heirs' right.
