In our locality, there is only one small masjid. Because there are many people attending the masjid for the Jumma Salah, the congregational pray is performed two times in the masjid. People attending the masjid go back to work after the prayer. My question is: can the first congregational pray be performed before the time of Zuhr begins?
A masjid is not a requirement for the establishment of the Jumma Salah. For this reason, the Jumma Salah can also be performed in the location mentioned in the question on the condition that it is performed in the time of Zuhr by an Imam and three people along with him. However, it is Makrooh Tahreemi (disliked) to repeat the prayer in a masjid where the Imam and the Muqtadis (those lead by the Imam in prayer) of that masjid have already performed it. This must be avoided.
And Allah knows best.
