Does an adopted girl deserve half of the housing as a bequest, and what is the share of the full brother and full sister in the inheritance?

If the legatee is not an heir, and the bequeathed amount does not exceed one-third of the estate, then the will is valid and should be executed before the division of the estate. The remaining estate, after the bequest, is to be divided among the brothers and sisters, with the male receiving the share of two females, provided that the deceased has no debts. The matter of inheritances is serious and complex; a mere fatwa is insufficient. Instead, it must be referred to the Sharia courts for investigation to ensure the rights of all parties.
