Is the greeting of the mosque prescribed in prayer halls where some of the obligatory prayers are performed?

Question:
He says: Honorable Shaykh, may Allah grant you success, is the greeting of the mosque prayed in a prayer hall where we only pray one obligatory prayer?

Answer:
No, this is a prayer hall, not a mosque. It is permissible to sell it, and it is permissible for a wall to enter it. This is not a mosque, and it does not require the greeting of the mosque when you enter it. However, you pray the rawatib (the regular voluntary prayers attached to the obligatory ones) that come before the obligatory prayer; you pray them. Yes.
