What is the share of the full sister from the father in the inheritance of her father, who passed away 23 years ago, and how is her share estimated after her brother invested the inheritance in several properties?

The sister's share in this case is her share of the currently existing buildings, as long as they are from the growth and profit of the building left by the father. The brother's action does not remove the inheritance from its origin, whether with or without her consent. If his action was for the benefit of all, the matter is clear. But if it was for his benefit or the benefit of other heirs without her consent, then he is in the position of a usurper. Scholars have stipulated that the profit from usurped money and everything that originates from it reverts to its owner, citing the Prophet's (PBUH) saying: "Whoever cultivates in the land of a people without their permission, he gets nothing from the cultivation, but he gets his expenses," and his saying: "A tyrannical root has no right." Furthermore, the brother has prevented the sister from benefiting from her right for a long time and has resided in one of the dwellings without paying rent. Therefore, the brother must fear Allah and pay his sister her full right.
