Is it permissible to say all Takbirs, the Samiallah, the Bihawlillah, and the Taslim aloud during Zuhr and Asr prayers? Additionally, can we recite the Bismillah aloud before Surah Fatiha and other Surahs in these prayers?
Saying all the Takbir and other sayings in Zuhr and Asr aloud is permissible. Reciting the AlHamd and the other Sura should not be aloud in Zuhr and Asr. Reciting Bismillah Arrahman Arraheem aloud is recommended in Zuhr and Asr, while it is obligatory in Maghrib, Isha and Farr prayers.
Wassalam.
