Tarawih (Arabic: تَّرَاوِيح, romanized: tarāwīḥ) are special Sunnah prayers involving reading long portions of the Quran, and performing up to 20 rakahs (cycles of prostrations required in Islamic prayer), which are performed only in the Islamic month of Ramadan. The entire Quran is recited in the Tarawih prayers at a mosque, typically at the rate of one Juz' per night.
