Is it true that not dividing the inheritance during the father's lifetime nullifies the right of his heirs to it? And what is the ruling on the governmental (miri) division in Islam?

Whoever is alive after the death of their inheritee, inherits, even if they die before the division of the inheritance. This is agreed upon by scholars. The benefit of inheriting from the deceased is that their legal heirs inherit their share in the inheritance. This right is not forfeited by the passage of time, as Allah Almighty says: {For men is a share of what the parents and close relatives leave, and for women is a share of what the parents and close relatives leave, be it little or much - a share ordained.} [An-Nisa: 7].

Therefore, delaying the division of your grandfather's inheritance after your father's death does not deprive you of it. And it is not permissible for there to be a law that contradicts this, because Allah Almighty undertook the exposition of matters of inheritance, so it is not an area for ijtihad (independent reasoning).

What is called "Miri division" (a historical system of land division) which equalizes the share of male and female is invalid in Islam, because it contradicts His saying, the Almighty: {Allah instructs you concerning your children: for the male, what is equal to the share of two females.} [An-Nisa: 11] and His saying, the Almighty: {And if there are brothers and sisters, male and female, then for the male is the share of two females. Allah makes clear to you so that you do not go astray. And Allah is knowing of all things.} [An-Nisa: 176]. Deviating from this is misguidance.
