and so you figure that “a very big reason” is that the wife has to be barren? i’ve seen plently of successful cases involving polygamy including my own family. Allah has allowed this but it also comes with a big obligation. Seriously if you don’t like it and don’t want to be a part of it then fine, it doesn’t matter to me, but don’t start coming up with your own interpretations of what is said in the Quran and passing them off as facts.
