If you enter the prayer while the imam is bowing, is one takbir sufficient, or are two takbirs required?

Question:
I entered the prayer while the imam was bowing. I said the takbir for entering the prayer, then the takbir for bowing, without reciting the opening supplication or the opening dhikr, for fear that he would rise from bowing and for fear that I would miss the rak'ah. Does one takbir suffice in this situation, or are two takbirs required? May Allah reward you with good.

Answer:
If one comes while the imam is in bowing, he says the takbir for entering the prayer before he bends, because the takbir for entering the prayer must be said while standing. Then he bends for bowing. If he comes with another takbir, it is a recommended practice (sunnah). If he wishes to suffice with the takbir for entering the prayer, he does not suffice; the takbir for bowing in this case is not of this nature.
A pleasant takbir. As for the takbir for bowing in other than this case, it is among the obligatory acts of the prayer. As for the opening supplication, it has no place here.
Because he cannot perform the correction and catch the bowing. In fact, reciting al-Fatihah is dropped from him in this case, and it is a pillar of the prayer. Even according to those who say it is obligatory for the ma'mum—most of them hold this case—they say that reciting al-Fatihah is dropped from him, but he catches the bowing.
