The Ruling on the Second Congregational Prayer in the Mosque

Question:
He says: If I enter the mosque and find that the prayer has already been completed, is it better for me to pray alone or with another man for the virtue of the congregation? And what is the ruling on a second congregation in the mosque?

Answer:
If you find one person or more, it is obligatory for you to pray in congregation; it is not permissible for you to pray alone. If you find one person or more, you pray in congregation with them and do not pray alone, because the congregation is obligatory, and it is an individual obligation. However, if you do not find anyone, there is no harm in establishing a second congregation if the first congregation has passed; there is no harm. As for establishing two congregations in a mosque while the first has not passed—where some people are praying the congregation and others come to pray another congregation—this is not permissible. This is division, and it is not permissible.
