Ref. No. 939/41-1100 A
In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
Government has asked Muslims to suspend the Friday congregational prayer for some days as part of efforts to stem the spread of the novel coronavirus known as COVID-19. Hence, all are requested to follow strictly the guidelines of the government to be protected from coronavirus pandemic.
In this situation, Imam and Muazzin along with some people (cleaning workers etc.) should offer Friday congregational prayer in masjid and others should stay at home and offer all prayers therein. Masjid should remain closed for general public for all prayers including Friday prayer amid coronavirus pandemic. It is a good measure for safety.
And Allah knows best
