All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
The Friday prayer is valid whether it is performed in a mosque or somewhere else, this is the opinion of the Shaafi’i and Hanbali scholars . However, according to the most correct opinion establishing it in more than one place is not allowed except if the place can not accommodate all people or that it is far enough that it becomes difficult for people to reach it. In such a case, establishing it in many places, be it a big mosque or a small one or any place other than a mosque, all such cases are allowed, but only according to necessity.
Know that some of the objectives for establishing the Friday prayer is for the Muslims to get together, know each other, develop cooperation between them and to achieve many other benefits. See Fatwa 90374.
Therefore, we advise those who started praying the Friday prayer in a new place to come back to perform prayers with their Muslim brothers and they should not disunite the Muslims without any Islamicly valid reason.
Allaah Knows best.
