Tarawih prayers begin from the first Moon-sighted evening—the start of Ramadan—to second moon-sighted evening—the last day of Ramadan. This prayer is performed in congregation during Ramadan of the
Islamic calendar, after
Isha, and before
witr, which is also prayed following the imam, who leads the prayer aloud in one or three raka'āts unlike for the eleven other months. Tarawih prayers are prayed in pairs. According to the
Hanafi,
Maliki,
Shafi'i, and
Hanbali schools of
Sunni Islam, the standard number of
raka'āt is twenty since it is referred to in a narration in
al-Muwatta, which states: "In the time of
Umar, the people used to offer 20 raka'āt." However, it clearly mentions in the before the said narration that when Umar assigned
Ubayy ibn Ka'b and
Tamim al-Dari the duty lead the Tarawih, he ordered them to offer 11 raka'āt (eight of Tarawih and three of witr). Sunni Muslims believe it is customary to attempt a
takmil ("complete recitation") of the
Quran as one of the religious observances of Ramadan, by reciting at least one ''
juz''' per night in tarawih. Tarawih prayers are considered
Sunnah, or meritorious but not obligatory. However, it is believed that the reward for them is great, as it is the Sunnah of
Muhammad and is reported in multiple authentic
hadiths. Muhammad—according to
Abu Hurayra—said: "Whoever stands with the
imam (in Taraweeh prayer) until he finishes, it is equivalent to spending the whole night in prayer." The hadith was used as a proof by Imam
Ahmad ibn Hanbal. ==Background==
