If you join the imam in a prayer recited quietly and he bows before you have finished al-Fatihah, do you bow?

Question:
He says: Honorable Shaykh, may Allah grant you success. A person says: I enter the prayer with the imam from the beginning, and then while I am reciting al-Fatihah in the prayer recited quietly, the imam bows and I have not finished al-Fatihah yet. What do I do? Do I bow with the imam even if I have not finished al-Fatihah, or what do I do? I know that this happens to me often.

Answer:
You bow with the imam. The Prophet (peace and blessings be upon him) said: It is necessary that you bow with him even if you have not finished al-Fatihah. When Abu Bakr (may Allah be pleased with him) came and the Prophet (peace and blessings be upon him) was bowing, he bowed with him and had not recited al-Fatihah, and the Prophet (peace and blessings be upon him) approved of that for him. Yes.
