Are the expenses for male and female children equal in terms of allowance and completing their education during their father's lifetime and after his death? And are some children deprived of their allowance or completing their education due to the father's lack of a will? And if the income from commercial shops is distributed among all children, is it obligatory for those who have no income to pay for living expenses from their share? And should the distribution be for the male like the share of two females? And upon whom is the responsibility for the daughter's expenses after her father's death, whether she has wealth or not?

Spending on children should be according to their needs, and fairness is not required in it; for fairness is achieved by fulfilling each one's need. As for gifts and endowments, fairness is required among the children, unless there is a legitimate Islamic justification.

If one of the children needs to marry, and the father marries him off, the father is not obligated to give the others the same, but he is obligated to marry them off if they wish to marry.

If the father spends on his children according to his ability and their needs, and does not intend to discriminate, there is no harm in that.

And if the allocation to one of the children is due to a legitimate excuse, such as need, blindness, a large family, or engagement in seeking knowledge, or if giving is withheld from another due to his immorality, then there is no harm in that.

As for the daughter's maintenance, if she has wealth, her maintenance is from her wealth. Otherwise, her maintenance is on her father if he is well-off. If the father dies and she has no wealth, her maintenance is on her relatives and kin. If she has no one to spend on her and she is able to earn, then she must earn to spend on herself.

As for the father's will to his son for maintenance from his property, it is not valid except with the consent of the heirs. All that the father left behind is an inheritance to be divided among the heirs according to each one's share, and for the male is the like of the share of two females.
