Catching up with the congregation

Question:
How does one catch up with the congregation, O Shaykh?

Answer:
One catches up with the congregation by catching up with one rak'ah; this is the correct view. Some say one catches up by saying the takbir before the imam's taslim, and this is what is in the text of al-Zad. As for the one who says that whoever says the takbir before his imam's taslim has caught up with the prayer, the stronger position is that the congregation is not caught up with unless one catches up with a complete rak'ah, just as with the Friday prayer. It is not caught up with unless one catches up with a complete rak'ah. Yes.
