Is a wife entitled to ask her husband about the amount of the monthly budget, expenses, and savings, especially if she gives him her entire salary?

The Sharia (definition) obligates the husband to spend on his wife in a reasonable manner, and the wife is not obliged to spend except with her consent. It is not permissible for the husband to take anything from his wife's money unless she willingly gives it; otherwise, what he takes is unlawful gain. If the husband spends on his wife in a reasonable manner, it is not her right to know the amount he saves. However, if the wife contributes her salary to family expenses, she has the right to know where and how her money is spent, and the proportion she bears of the budget; otherwise, she has the right to refrain from spending.
