Namaz or Salat (الصلاة ) comes in Quran 64 times in 61 ayas (or verses)

It means getting up at night (preferably in the last third of night) to perform salat, God praying, and reciting Quran; the minimum of it is the salat for two Raka'ats.

Nothing special to recite in Taraweeh Salat (or namaz). You can recite whatever is convenient to you and of what length of verses you can afford and manage.

However, some prefer to take this opportunity and recite the full Quran in order over the full month of Ramadan; from Surah Al Baqarah until end of Quran. In each night of Taraweeh salat, one Juz' (or part, around 20 pages) is recited.

Offering Salat (prayer) five times a day is obligatory.

Answer 2:

The Quran recommends Salaah to bring us closer to God and keep us away from evil. Regularly performing Salaah (5 times a day), should create God consciousness.
