Is it obligatory for children to pay a monthly sum to their mother—given the presence of a financially capable father—and is the father entitled to demand a third of his children's salaries?

If the father is wealthy and the mother is provided for by his expenditure, then the children are not obligated to spend on them. Spending becomes obligatory if the parents are poor and the child is wealthy. As for the maid's wages, they are not obligatory to be paid unless the parents need her and cannot afford her wages. A father is permitted to take from his son's wealth under three conditions: the need for the money, not harming the son, and not giving it to another child. As for whether a mother can take from her son's wealth like a father, there is a difference of opinion among jurists. The preponderant view is that both parents are allowed to take when in need, provided the conditions are met. Children, for their part, must observe the rights of their parents in righteousness and benevolence.
