How a latecomer prays when he finds the imam in the final tashahhud

Question:
He also says in his last question: What is the ruling if the ma'mum joins the imam while the imam is in the final tashahhud? Does he recite the tashahhud with the imam, or is he required to remain silent until the imam says the taslim, and then he stands to complete his prayer?
And finally, please accept my thanks to you.

Answer:
If the latecomer joins the imam in the tashahhud, the best is for him to recite the tashahhud; due to the generality of his statement (peace and blessings be upon him): So the best is to recite this, and it does not appear to me that it is obligatory for him; because it is not in its proper place. So the most apparent is that it is not obligatory, but if he does so and recites it; because it is dhikr; and because it is good, and it contains a type of following the imam, then this is better and more appropriate, but it is not obligatory; because it is not in the place of his tashahhud; because the tashahhud is only after two rak'ahs, or after the last one, and this rak'ah is not the last one for him, and it is not the place of two rak'ahs, rather it is not considered anything for him, rather he sits only as a follower, then when he stands he recites two rak'ahs, then he sits for the first tashahhud, then he recites what remains upon him: one from Maghrib, and two from Zuhr, 'Asr, and 'Isha', and if it was Fajr he prays two rak'ahs, stands and recites the two rak'ahs, this indicates that this sitting is not counted for him, so if he recites the tahiyat because it is dhikr and he followed the imam, then this is good, as for the obligation, it does not appear that it is obligatory for him, yes.
