A:The Imam recites on your behalf. You will not recite Surah Faatihah and Surah at all. When the Salaah commences, recite Thanaa and thereafter remain silent. Thanaa is read only in the first rakaat. Recite the Tasbeehs of Ruku, Tahmeed, Tasbeehs of sajdah, tashahhud, Durood, Du’aa after Durood and salaam. This applies when you are following an Imam. If you are alone then you will recite everything.
