I found the wording of this response to be very strange:
Now I know the response is to the question in the link, but the claim of polygamy being impermissible is general.
An earlier answer (2011) by Sh. Faraz himself says it is permissible, but wrong without consulting a scholar.
I browsed a few more fatwas and not all made the claim that is was impermissible, but all discouraged polygamy and most linked to the above 2 fatwas for further reading.
Who knows , in 100 years, polygamy may be deemed haram in hanafi fiqh.
This is not a debate as to whether it is wise to marry more than one wife , it is making something forbidden which is halal.
