Q: Does one have to read Tasmiyya loud before surah Baqarah? And what if it wasn't read then?
A: It is necessary to read Bismillah aloud at least once during the Taraweeh khatam. If this is not done then the Quran of the muqtadees will not be complete. However, the tasmiyah could be rendered before any surah. If it was not read before Surah Baqarah, it should be read later during the taraweeh.
