The additional nightly prayers commonly performed during Ramadan are called tarawih.
Tarawih prayers are Sunni Muslim devotional prayers associated especially with Ramadan nights. They are commonly performed after the obligatory evening prayer, isha, and may be held in congregation at a mosque. Many worshippers listen as an imam recites long portions of the Quran over the course of the month.
The number of rakahs performed in tarawih varies among Muslim communities and legal traditions. This makes tarawih different from the two-rakah Eid prayer, whose basic form is a separate festival observance.
Tarawih is generally considered voluntary rather than one of the five obligatory daily prayers. Some Muslims perform it at home, while others attend a mosque. Practices also vary among Sunni and Shia communities.
