Establishing a second congregation in the Masjid

Q: What is the ruling on one who enters the Masjid (mosque) after the congregational Salah has begun and the Imam is a trustworthy Muslim, but that person ignores it and starts another congregational Salah somewhere else in the same Masjid? Is he entitled to do that? Kindly give us your Fatwa, may Allah reward you the best, and make you steadfast in making Allah's word most high.

A: It is not permissible to establish a second congregational Salah so long as the first one has not yet been concluded.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
