Is there any Sharia basis for restricting legal inheritance of Amiri lands, which equalizes the share of the male and that of the female?

The general rule in inheritance distribution is that a male receives the share of two females, except in cases such as consensual division (Qismat al-Muradaah), or full brothers and sisters from the mother's side (Akhwah li-Umm), or distant kin (Dhawi al-Arham) where males and females receive equal shares. As for the Amiri lands in Bilad al-Sham (the Levant), since they were conquered by force and are owned by the state, the ruler has the right to dispose of them as he deems beneficial. The equality between males and females in these lands arises from a grant by the state, and the law is to be applied so long as it does not contradict the texts of Islamic law.
