In loud prayers, you are not allowed to recite except the Fatiha. But ifyou don’t recite it, this is permissible because the Imam did that for you.

When reciting Surah Fatiha in congregation if I feel that I will not be able to complete the Surah before the Imam goes into ruku, what would be the better option in your opinion, to go into ruku or to speed up and finish it quickly
