Salat al-Jama‘ah (Congregational Prayer) or prayer in congregation (Jama'ah) is considered to have more social and spiritual benefit than praying by oneself. When praying in congregation, the people stand in straight parallel rows behind the chosen imam, facing qibla. The imam, who leads the congregation in salat, is usually chosen to be a scholar or the one who has the best knowledge of the Qur'an, preferably someone who has memorised it in its entirety (a hafiz). In the first row behind the Imam, if available, would be another hafiz to correct the Imam in case a mistake is made during the performance of the salat. The prayer is performed as normal, with the congregation following the actions and movements of the imam as he performs the salat.

​

Congregation prayer in a mosque, or masjid, is particularly encouraged for men and is optional for women. Muslim men are encouraged to offer as many of the five daily prayers in the mosque as possible, as the reward for doing so is at least 27 times greater than offering the prayer alone at home.
