How is inheritance divided among five sons and two daughters, one of whom is a full sister to the five sons and the other a half-sister (maternal half-sister)?

All sons and daughters inherit from their deceased mother, regardless of whether they are from the same husband or from different husbands. If the deceased leaves no other heirs, her estate is divided among them by ta'sib (agnatic inheritance), with the male receiving the share of two females, in accordance with His, the Almighty's, saying: "Allah instructs you concerning your children: for the male, what is equal to the share of two females." The estate is then divided into twelve shares, with the son receiving two shares and the daughter one share.

It is important to note that inheritance issues are serious and complex, and a mere fatwa is not sufficient. Rather, they must be brought before Sharia courts for investigation and to ensure there are no other heirs, wills, debts, or rights that take precedence over the heirs' rights, in order to guarantee everyone's rights.
