In regards to paritions or barriers in the masjid and their requirments
Shaikh Bin Baz rahimahullah said:
“The affair is spacious. It is not necessary to have severity in this. It can be a wall, a net, or curtain or other than that. All of that is good. All of that is permissible and all praise is due to Allah”
