Does the financial maintenance of wives vary according to the number of children?

Question:
If a man has multiple wives, and one of these wives has four sons, while the other has six, does he have to equalize their financial maintenance, or is he given a choice?

Answer:
No, each one is given the financial maintenance that befits her. The one with four children has a certain situation, the one with six has a different situation, and the one with eight has yet another situation. Each one is given what is appropriate for her and her children, and they are not on the same level; this is due to the difference in the number of children, whether many or few.
As for the wife herself, she is treated like the other wife he has, and he must be just between the two. Some scholars said that the status of each one’s family and their social standing should be taken into consideration, but this is not the apparent view. Rather, it is obligatory to be just between them in food, clothing, and division of time, absolutely. Whether one is the daughter of the wealthy and the other is the daughter of the poor, it is obligatory to be just between them, whether in financial maintenance, clothing, housing, or division of time. Yes.
