Do daughters inherit from the wealth of their brothers if the inheritance left by the father was amassed by the father and sons together in one family?

If the deceased's heirs are limited to those mentioned, then the inheritance is divided as follows: The wife receives one-eighth due to the presence of a lineal descendant, based on the Almighty's saying: "But if you have a child, then for them is one eighth of what you leave." The remainder is divided among the children by way of 'asabah (agnatic succession), with the male receiving the equivalent of the share of two females, based on the Almighty's saying: "Allah instructs you concerning your children: for the male, what is equal to the share of two females." The children's assistance to their father and their work with him in investing his money does not affect the division of the inheritance; the default assumption for their work is that it was a voluntary contribution, unless they explicitly declared that they did not intend it as a donation or if it is the custom of their country, in which case they would be compensated for their work.
