Is it permissible to perform the same obligatory prayer in congregation more than once in the same place and at different times?

If you have prayed the obligatory prayer in a congregation, do not repeat it with another congregation, unless there is a legitimate reason, such as giving charity to someone who missed the prayer by praying with them. As for establishing another congregation after the regular Imam's congregation has concluded in the mosque, there is a difference of opinion among scholars regarding this.
