How is the inheritance divided between: a son, two daughters, a daughter of a deceased son, and her guardian?

The method of inheritance distribution cannot be clarified until the heirs are definitively identified, without any ambiguity. This can be done via the dedicated link.

If the deceased left no heirs other than those mentioned, then the inheritance goes to the son and the two daughters by ta'sib (residuary inheritance), with the male receiving the share of two females, based on the verse: "Allah instructs you concerning your children: for the male, what is equal to the share of two females." The granddaughter receives nothing if her father died before his own father, because she is excluded by the son through complete exclusion.

Thus, the inheritance is divided into three shares: two shares for the son and one share for the daughter.
