The literal meaning of these two words is "the day of congregation" that is Friday. Muslims gather in the masjid (mosque) for a khutba (sermon or address) followed by Salat led by an Imam. After the Salat, people meet each other in the masjid and may visit relatives and friends. In Islam there is no Sabbath, therefore, there is no mandatory closing of businesses on Friday except for the duration of congregational services. However, in a majority of Muslim countries, Friday is the weekly holiday, sometimes combined with Thursday or Saturday. In the West, Muslims take a couple of hours from their jobs or businesses to go to the mosque on Friday. The Friday prayer, held in the early afternoon, in general, lasts for less than an hour.

In large work places where many Muslims are employed, Muslims use a room and prepare it for the Friday Salat. In some places a community center room is rented for a couple of hours on Friday for holding the congregation. Since, a part of the Salat requires prostrating and sitting on the floor, it is covered with clean sheets or rugs.
