Is polygyny with a middle-class standard of living better than not having polygyny with a high material standard of living for me and my family, and which of them yields greater reward?

It is not permissible to issue a ruling on the superiority of polygyny or limiting oneself to one wife in terms of reward; for the ruling varies according to the man's situation, his need for marriage, his ability to be just, his ability to fulfill the rights of his wives, and the impact of polygyny on him and his family. This requires balancing and considering the consequences, and observing the man's motives, sincerity, and devotion.
