Peace be upon you. What is the ruling on Tarawih prayer?

Tarawih prayer is a confirmed Sunnah. The Prophet, peace and blessings be upon him, instituted it and encouraged it with his saying: "Whoever observes night prayer in Ramadan out of faith and seeking reward, his past sins will be forgiven." The Prophet, peace and blessings be upon him, prayed with the Companions for several nights, then stopped, fearing that it would be made obligatory for them. After him, Umar ibn al-Khattab gathered the people behind a single Imam.
