Question 21: A man has two wives; one of them is an employee who receives a monthly salary, which she spends as she wishes without giving him any of it. He pays the expenses of the house, such as electricity and telephone bills. She does not help him with any part of her salary. When she buys a piece of cloth, it is he who pays the dressmaker’s fees. The other wife is a housewife. She does not have a source of income, but she may get some money from her daughters who are employees. However, it is not enough to fulfill all her needs. The husband pays for the electricity and telephone bills.
If he gives his second wife – the housewife – some money to fulfill her needs,does he have to give the other wife the same amount in order to observe equity between them? Does he have to give something to the working wife every time he gives something to his wife who does not work?
