If a worshiper catches the imam in bowing, how many times does he say the takbir?

Question:
He says: Honorable Shaykh, may Allah grant you success, if a worshiper comes and the imam is bowing, does he say the takbir once or twice? And if it is once, does he intend it for the takbir of entering prayer or for the bowing?

Answer:
As for the takbir of entering prayer, it is obligatory and it is a pillar of the prayer. He says it while standing. Then the second takbir, which is for the bowing, is a recommended practice (sunnah) in this place. In this place, it is a recommended practice (sunnah). If he wishes, he says it, and if he wishes, he limits himself to the takbir of entering prayer. Yes.
