No, this is not a masjid. This is a prayer hall or room and it doesn’t takethe ruling of masjids that should be owned for the purpose of prayers and it
is made as endowments.

And Allah knows best

There is a place that our brothers have rented and 5 prayers are being performed in our town AlhamduliLaah. This place is rented & under contract , can this place be considered as a Masjid?
