If a group of musaafirs in a city perform Zuhr in a house on Friday, do they perform with Jamaa't?

Answer

Firstly, understand that you are most unfortunate for not performing Jumuah in the city regardless of being musaafir. When the convenience exists for performing Jumuah, then being musaafir does not justify abandonment of Jumuah.

Anyhow, if someone opts for harming himself by preforming Zuhr in the house in a city, then he has to observe the following procedure:

Zuhr Salaat has to be performed individually, not in Jamaa't.

Zuhr should be performed without Athaan and Iqaamat.

Zuhr should be performed after Jumuah Salaat has been performed in the Musjids of the city.
