Catching a Rak'ah When the Imam Rises from Ruku'

Question:
Honorable Shaykh, may Allah grant you success. He says: I came to the mosque and the people were in ruku'. While I was saying the takbir and going into ruku', the imam was rising. Did I catch the rak'ah?

Answer:
If your hands reached your knees before the imam raised himself, then you caught the rak'ah. But if the imam raised himself before your hands reached your knees while you were bending, then you missed the rak'ah. Yes.
