What is the legal share of daughters from their father's inheritance, and is this right calculated before or after the prosperity of the shop's business? And what must the sons do to clear their father's liability?

1. Justice must be observed in a father's gift to his children. It is not permissible to favor some of them over others unless there is a legitimate Shariah justification. Otherwise, the gift shall be returned to the estate after his death. As for what the male children earned from trading with their father's money, with his and their sisters' consent, and with which they bought lands and cars, it is their private property if the money is equivalent to their fair wages for their effort and work.

2. The money spent by the children and their mother to develop the business is either a gift or a loan, not a partnership. The business and the shop are the father's property and will pass to all his heirs according to their Shariah-ordained shares. Whatever the children spent on themselves from these funds is considered compensation for their efforts.

3. The nominal registration of the shop in the name of the eldest brother, the sister, and the mother does not transfer ownership; the intention behind the action matters, not just the words. The sisters' request to retract an ineffective waiver is meaningless, and they have the right to claim their share of their father's inheritance from the shop, the house, or the business funds.
