Question:
How is the statement of the Commander of the Faithful, 'Umar (may Allah be pleased with him), "What a good innovation this is" answered?

Answer:
What is a legal innovation? This is a linguistic innovation. A linguistic innovation. Innovations in religion are not permissible, not with 'Umar or anyone else. His intention was the linguistic innovation: something that had no precedent, such as gathering them behind a single imam. They used to pray in scattered groups, so gathering them behind one imam is considered, from the linguistic perspective, an innovation because it was something not said before; it was not said before, so it is considered an innovation. A linguistic innovation, not a legal innovation, because the tarawih prayer is not an innovation, my brothers. Praying it in congregation is from the Sunnah of the Messenger of Allah (peace and blessings be upon him). 'Umar merely revived the Sunnah of the Messenger by gathering them behind a single imam. They used to pray the tarawih behind the Messenger of Allah (peace and blessings be upon him) on nights of Ramadan, but he delayed it out of fear that it would become obligatory for them. He (peace and blessings be upon him) prayed with them for nights. So, the tarawih prayer in congregation behind a single imam is from the Sunnah of the Messenger of Allah (peace and blessings be upon him) and is not an innovation. We must know these matters. Yes.
