In Oman, the place of prayer for us, the Mosque are still not fully opened. The Friday congregation are held in a limited form. We can't say the Friday important prayer due to this restriction. This type of restrictions are seen, more or less, in different part of the world, just like you have mentioned about that gurudwara in your post.

In such case, we are really in dilemma and sometimes, we feel it as a wrong approach. We, mankind, are failed to contain the virus. It is the high time to maximize our prayer to the God but we aren't allowed to pray in His house (we consider Mosque as a house of God). Are we doing it right?
