What is the ruling on performing the Tarawih prayer in congregation?

Although it is generally more virtuous to perform voluntary prayers individually, performing the Tarawih prayer in congregation is established by the practice of the Prophet Muhammad (peace be upon him). Indeed, the Prophet led the Tarawih prayer in congregation several times, but later refrained from doing so out of concern that it might become obligatory (Bukhari, Salat al-Tarawih, 1 [2012]; Muslim, Salat al-Musafirin, 177-178 [761]).

When Umar (may Allah be pleased with him) became caliph, he observed that people were performing the Tarawih prayer in a scattered manner and thought it would be more appropriate to reestablish the practice of praying in congregation. After consulting with the Companions, he reinstated the congregational performance of this prayer. Upon seeing the people performing the prayer with devotion, he expressed his satisfaction by saying, “What a good custom this is” (Bukhari, Salat al-Tarawih, 1 [2010]). Ali (may Allah be pleased with him) prayed, “May Allah illuminate Umar’s grave as he has illuminated our mosques with the blessings of Tarawih” (Ibn Asakir, Tarikh Madinat Dimashq, 44/280 [9808]).
