You do not catch the congregation by entering with the imam in the final tashahhud
If I enter the mosque and the imam is in the final tashahhud, what should I do?
If you enter the mosque and the imam is in the final tashahhud, enter with him. Say the takbir of intention while standing, then sit down. When he says the taslim, you perform what remains for you.

The questioner: Is it considered that I caught the congregation?The Shaykh: The correct view is that you did not catch it, but you are rewarded for your intention and for your presence in the mosque.
