question #2 Sahih al-Bukhari 772, Book 10, Hadith 166 : Is reciting Surah Al-Fatiha alone sufficient in prayer, and what is the benefit of reciting additional verses?

The Qur’an is recited in every prayer and in those prayers in which Allah’s Messenger (ﷺ) recited aloud for
us, we recite aloud in the same prayers for you; and the prayers in which the Prophet (ﷺ) recited quietly,
we recite quietly. If you recite “Al-Fatiha” only it is sufficient but if you recite something else in
addition, it is better.
