If a person enters the prayer while the imam is in the final tashahhud, does he pray with the imam or establish a second congregation?

Question:
Honorable Shaykh, may Allah grant you success. The questioner asks: What is better if a person enters the prayer while the imam is in the final rak'ah, in the final tashahhud? Does he pray with the imam or establish a second congregation?

Answer:
If he knows that people are coming, he waits until they establish a congregation after the imam's taslim. They establish it after the imam's taslim, while the imam has not yet finished. However, if he does not know about anyone, he joins the imam and does not miss what he catches up with. He joins the imam and gains the virtue and following of the imam, and completes his prayer. Yes.
