Establishing a Second Congregation and the Imam in the Tashahhud

Question:
Honorable Shaykh, may Allah grant you success. He says: What is the ruling on establishing a second congregation while the imam is still in the tashahhud and has not yet said the taslim?

Answer:
It is not established as long as the imam has not said the taslim. It is not permissible to establish a second congregation, even if people come and say, “We are a congregation, we want to pray,” and they establish the prayer while the imam has not said the taslim. This is not permissible; it is forbidden. They do not establish it until after the imam says the taslim. Yes.
