The Ma'mum Entering the Prayer with the Imam in the Final Tashahhud

Question:
Honorable Shaykh, may Allah grant you success. He says: Some scholars cited the hadith of Abu Qatadah as evidence that if the ma'mum catches up with the imam, even in the final tashahhud, he should enter the prayer with him directly. He says: If the ma'mum catches up with the imam, even in the final tashahhud, he should enter with him directly and not wait for another congregation, based on the general wording of the verse: "So whatever you catch up with, pray." Is this evidence sound?

Answer:
In our view, if he knows that a group is coming to pray, he should wait for them to pray with them, because the congregation is missed if he does not catch up with one rak'ah. If he does not catch up with one rak'ah with the imam, the congregation is missed. However, if he does not know that anyone is coming and does not expect anyone to come, he should enter with the imam to obtain the reward of following the imam, so that he does not miss this. Yes.
