How the one who joins the prayer late performs the final tashahhud with the imam

Question:
The questioner: May Allah preserve you, O Shaykh. Regarding the one who joins the prayer late in his final tashahhud, does he recite the first half of the tashahhud or the whole of it? And if it is half of the tashahhud, what about the time he remains silent until the imam says the taslim?

Answer:
He performs the tashahhud and what accompanies it following the imam. Then, when the imam says the taslim, he stands up and makes up what is due from him. He performs the tashahhud, the prayer upon the Prophet (peace and blessings be upon him), and the supplication. Then he stands up after the imam says the taslim: So he recites it following the imam. Even if it does not suffice for him, he recites it following the imam, just as if he had come and the imam had already prayed one rak'ah. He would sit with him in the second rak'ah for the first tashahhud, even though he is not in the place of his own tashahhud, having prayed only one rak'ah, but he follows the imam. So the point is that this is following the imam, and praise be to Allah. Yes.
