During the month of Ramadan, many Muslims attend Taraweeh prayer. Taraweeh prayer starts after Isha every day. It first starts on the day before the fasting period begins until the day before Eid. The Quran was revealed during this month. The Taraweeh prayer is Sunnah, which does not mean it is compulsory however it is suggested to take part in these prayers to strengthen one's faith.
The aim of the Taraweeh prayer is to finish the Quran during the month of Ramadan. The Imam will lead the prayers starting from ‘Al-Baqara’ until the Surat ‘An-Nas.’ Usually there will be 20 prayers, each prayer consisting of two rakat. Sometimes Taraweeh prayers can take long into the night, thus some Mosques just have eight prayers to allow everyone to go to their homes safely and not extremely late.
This is then followed by a prayer called witr, which consists of three Rakat, where there is a Dua after the third rakat. This is a closing of the Salat, this means you cannot pray any more prayers after this, thus if you plan to pray more prayers during the night then you should not pray witr after Taraweeh.
Every day, the Imam will read one juz of the Quran, meaning the Quran will be finished within around thirty days. The length will be adjusted accordingly depending on when it is Eid. Since one juz is being read each day it can be extremely tiring for many, thus some prefer to have a chair handy when they feel they are getting tired.
Many people like to follow reading the Quran during Taraweeh and this is allowed to use the Quran during Taraweeh because it is a Sunnah prayer, in obligatory/fard prayers this will not be allowed. However, one is not allowed to put the Quran onto the floor so the Quran must be placed on a raised area on top of another object. Many just prefer to listen to the recitation of the Quran instead of reading it.
If you can pray Taraweeh prayers, it is best to. Make sure that you always have a bottle of water and do not fill yourself too much at Iftaar and after because it can make Taraweeh prayers very difficult. Pray as much as you can and when you are feeling tired you can sit down during prayer. Many Mosques are air-conditioned so it should not get hot during Taraweeh, however if you speak with those in charge of Mosque welfare an arrangement should be able to allow Muslims to pray in a cool environment.
