If your leaving work to pray Jumu`ah will adversely affect the factory, such as the risk of machines breaking down or fires breaking out etc., and there are other men in the factory with you, you can pray Jumu`ah in the factory, if the factory is inside the town, or it is outside and you can hear the Adhan without the aid of loudspeakers.

Those who attend Jumu`ah prayers have to be silent and listen attentively to the Imam. It is not permissible to talk during the Khutbah except in the cases indicated by the evidence, such as speaking to the Khatib or responding to him, or in cases of necessity such as saving a blind man from falling and so on.

The virtues Friday include: 1- on it is the Friday prayer, which is the best of prayers, 2- praying Fajr in congregation on Fridays is the best prayer that the Muslim can pray during the week, and 3-whoever dies during the day or night of Friday, Allah will protect him from the trial of the grave.
