You don't need to even do it, you just choose to (poly)
Allah never said a man is required to marry more than one wife, but Allah does teach men to care about their wife with empathy, compassion, and consideration. So if a man chooses poly, especially in today’s time, he needs to be honest about whether he truly cares about her feelings or not.
If the situation were reversed, most men would not be comfortable with the idea of their wife wanting multiple husbands either.
I see this more as a matter of morals and character. It shows what a man chooses to prioritize and what kind of husband he wants to be.
That’s my take on this.
And just like a certain community I posted something similar where they totally did not talk about the topic but wanted to defend the ruling instead, I will not take time to respond to that because obviously that's not what we're even talking about right now, so lets stay on topic. But I honestly believe they don't find it wrong or something to even consider because it has been made permissible. That's why I fall it back to a moral and character issue. But I understand how can something Allah has made permissible is something that lack moral and character, then that's when I bring the justification that everything in this world is a test. This in itself could be a test for all we know. And again, it isn't rulling that you MUST, only that you choose to do.
