Firstly:
If the grandfather gave wealth to someof his daughters because they were in need of it, either because of poverty,sickness or some other reason that dictated that they be singled out for that,there is no blame on him for that and he does not have to give to the rest ofhis children except in the case of need.

Secondly:
If a father dies and leaves behind a sonand six daughters, and there is no heir apart from them, then the son getsdouble the share of each daughter, because Allah, may He be exalted, says(interpretation of the meaning):
“to the male, aportion equal to that of two females”
[an-Nisa’ 4:11].
If the price of the land is 1000 rupees,then your father gets 250 rupees and each of his sisters gets 125 rupees.
This is how everything that was leftbehind by the grandfather after he died should be divided: the house in whichhe used to live, and in which your father is living and taking care of itsmaintenance, and everything else he left behind of money, property and land.
The basic principle is that the estateshould be divided immediately after the death of the owner of the wealth, becausedelaying it may come under the heading of neglecting some people’s rights orlead to rights being withheld from some.
But if your father had made an agreementwith his sisters to sell the house in the future, with their willing consent,there is nothing wrong with that.
