What is the ruling on not attending congregational prayers in the mosque for Muslims residing in Europe, where it is difficult to reach mosques and the adhan is not called?

Congregational prayer is obligatory for every adult, capable man who hears the call [to prayer] with the customary sound. If the mosque is far away and the call is not heard, then attendance is not obligatory. However, it is recommended to be keen on going to the mosque due to the great reward it offers and the strengthening of brotherly bonds. As for Friday prayer, it is obligatory for everyone who is in the city or village where Friday prayer is established, whether they hear the call or not, by scholarly consensus. It is recommended to establish congregational prayer at home or with neighbors for those who do not go to the mosque.
