Salaah

Following the Jamaat Salaah of the Haram from the Hotel Jamaat Khaana

Q: Nowadays, some people are performing salaah in the hotel near the Musjid al Haraam while following the jamaat of Musjid al Haraam. The hotel has speakers installed and the recitation of the Imaam of Musjid al Haraam can easily be heard. However, since the Imaam is not present infront of the muqtadis, I am doubting whether the salaah is valid or not. Is it permissible for people to follow the Imaam in salaah while in their hotel rooms? Similarly, is it permissible to follow the Imaam in the hotel jamaat khaana? 

Reciting Surah Faatihah behind the imaam

Q: My question is regarding the method of jamaat namaz:

1. If someone is offering namaaz with jamaat, should he be required to recite “Surah-fatiha” and a surah after that if the imam is reciting it?

2. Now in the case of Zuhr and Asr prayers (when imam is not reciting loudly Surah fatiha and Surah) do the people have to recite it or should they simply stand quiet?

3. In the last 2 rakats of a farz namaaz, I know that surahs are not recited after surah fatiha, I just want to confirm this from you?

4. If I join the jamaat in the rukooh of the first rakaat, I don’t need to repeat the 1st rakaat (this is what I understand); now when will I recite the thana “subhanakaALLAH...” ?
