There have been different opinions about whether the ‘Bismillah’ at the beginning of Surah Al Fatiha is part of the Surah or not. For all other Surahs (exception for Surah Tawbah), Bismillah is mentioned prior to the first ayah of the Surah. Yet, the majority of the time it is not said in the loud salahs.
Is Surah Al Fatiha an exception to the regard? Shaykh Mohammed Mana discusses.
