Equality among Wives
1. If a person has more than one wife it is wâjib upon him to treat each one equally. Whatever he gives to one wife, the other wife also has the right to claim something equal to that in value. This rule of equality applies to all types of wives, i.e. whether both were virgins at the time of marriage, both were previously married or one was a virgin at the time of marriage while the other had been previously married. If he spends one night with one wife, he will have to spend one night with the other wife as well. If he spends two or three nights with one wife, he will have to do the same with the other wife as well. Whatever wealth, jewellery, clothes, etc. he gives to one wife, the other wife also has the right to claim something equal to that in value.
