Fiqh-us-Sunnah Volume 2, Supererogatory Prayer, Fiqh 2.134.

It is valid to perform the Jumu’ah salah in any country, city, mosque, any building in a city, or in any space in a city as it also is valid to have it performed in more than one place. ‘Umar wrote the following to the people of Bahrain: “Offer the Jumu’ah salah wherever you may be.” This is related by Ibn abi Shaibah. Ahmad holds its chain to be good. This includes both the cities and countryside.

Ibn ‘Abbas says: “The first Friday salah that was performed in Islam, after the Friday salah in the mosque of the Messenger of Allah sallallahu alehi wasallam in Medinah, was in Jawa’i, a village in Bahrain.” This is related by al-Bukhari and Abu Dawud.

Al-Laith ibn Sa’d reports that the people of Egypt and of the surrounding sea-shore would perform the Jumu’ah salah during the time of ‘Umar and ‘Uthman according to their orders. Some of the companions of the Prophet attended jumu’ah prayer with them. Ibn ‘Umar saw the people in the areas between Makkah and Medinah performing the Jumu’ah prayers, and he did not object to their action. This is related by ‘Abdurrazzaq with a sahih chain.
