Is it permissible for the ma'mum to recite the opening supplication while the imam is in the second rak'ah?

Question:
Honorable Shaykh, may Allah grant you success, he says: Does the ma'mum recite the opening supplication while the imam is in the second rak'ah?

Answer:
In the beginning of his prayer, yes. If he arrives while the imam is in the middle of the prayer, he enters, says the takbir for entering the state of ihram, and then recites the opening supplication, because it is the beginning of his prayer. What he catches up with the imam is the beginning of his prayer, and what he does after that is the end of his prayer. This is the correct opinion among the scholars. Yes.
