Praise be to Allah.
We put this question to Shaykh Muhammad ibn Saalih al-Uthaymeen, may Allaah preserve him, who replied as follows:
The rulings on mosques do not apply here. This is a musalla (prayer place), as is clear from the fact that it belongs to someone else, and the owner could sell it. It is a musalla and not a masjid (mosque), so the rulings on mosques do not apply to it.
Is it permissible to sell booklets and commercial announcements in it, or is that not appropriate in a musalla?
I think that this is not appropriate even in a musalla, because it distracts people from remembering Allaah, and inevitably disturbs those who are praying there.
What about menstruating women going there? Is it OK?
Yes. If they go and stay there, there is nothing wrong with that.
Is it necessary to pray Tahiyyat al-Masjid?
No, it is not necessary, but they should pray the usual Sunnah prayer.
Do you mean the Sunnah prayers between the two times of prayer?
And Allaah knows best.
