How is inheritance calculated for an heir who died, leaving behind: a mother, a wife, 2 granddaughters (daughter's daughters), 3 grandsons (son's sons' sons), 3 full brothers, and 3 full sisters, with debts owed by the deceased?

First, the deceased's debt must be settled from their estate before its distribution, as debt takes precedence over the heirs' rights.

If the deceased left no heirs other than those mentioned, the estate is divided as follows: The mother receives one-sixth (due to the existence of a inheriting descendant). The wife receives one-eighth (due to the existence of a inheriting descendant). The two granddaughters (daughters of the son) receive two-thirds (by consensus). The remainder after the fixed shares is taken by the three grandsons (sons of the son's son) by ta'sib (residuary inheritance) equally among them. The full brothers and full sisters receive nothing; they do not inherit when a son's son, no matter how far removed, is present.

The estate is divided into 72 shares: Mother: 12 shares. Wife: 9 shares. Two granddaughters (daughters of the son): 48 shares (24 shares for each). Each grandson (son of the son's son): 1 share.

This division is based on the premise that the sons of the son's son are of a lower rank than the son's two daughters.
