Women taking care of household responsibility from her salary while her husband is buoyant
Islam obliges the husband to spend on his wife and children. Allah has not saddled women with this responsibility even if they are rich. Allah has ordered the husband to spend on the wife and cater for their needs even if they are rich and the husbands are poor.
Even if the wife is rich, there is no religious rights nor custom that forces her to spend on the family from her income. It is better the husband makes her a full housewife and the husband takes responsibility of catering for the house and the children fully. Permitting a woman to work so that she can take part in the care of the expenses at home, despite the fact that the husband is wealthy, are acts of greed and stinginess that are not befitting for men.
