What does one do if he is unable to complete al-Fatihah with the imam?

Question:
The mosque imam says that they cannot allow us to recite al-Fatihah, especially when he bows quickly?

Answer:
The imam is a guarantor; the imam is a guarantor, as stated in the hadith. He is a guarantor for the prayer of those behind him, so he must be deliberate to enable those behind him to perform the pillars and obligatory acts of the prayer, and he must not rush them. Whatever deficiency occurs in their prayer is his responsibility.
He (peace and blessings be upon him) said: So the imam bears a great responsibility.
Then, the ma'mum (one praying behind the imam) must also not delay or be slow, but rather he should hasten to perform what Allah (Glorified and Exalted is He) has prescribed in the prayer, and not be slow in doing so. However, if it happens that the imam bows before the ma'mum has recited al-Fatihah or before he has completed it, he should bow with him, and his prayer is valid in this case. Yes.
