Is Friday Prayer obligatory upon more than three hundred men who are nomadic builders of villages, residing in each village for two years, or are they considered travelers? And what if there is a mosque next to them that holds Friday Prayer?

If your work requires you to travel between cities and villages, you are not permitted to pray Jumu'ah (Friday prayer) alone in your residences, due to your lack of permanent settlement, which is a condition for the validity of Jumu'ah according to the majority of scholars. If there is a congregational mosque near you that you can reach, Jumu'ah becomes obligatory upon you, because you are staying for more than four days. If there is no nearby congregational mosque, then you pray Dhuhr (noon prayer).
