You have to recite fatiha, and it is sunnah to recite some other surahs also. If you don’t recite the Fatiha in silent Rakah, your prayer is void and invalid.

While praying zuhr, asr or the raqahs in which the imam doesn’t recite loudely, do the people praying behind him have to recite for their own self or just wait silently for the Imam without reciting anything else and just go into rukuh whenever he says allah hu Akbar ?

Suppose i recite sura alaq after fatiha in salah & finished recitation with it. Should i perform sujud at-tilawa immediately then stand up again then go to ruku then go to sujud? Or is it sufficient to go to ruku then go to sujud?
