Praying the odd-numbered prayer (witr) in congregation after the Ramadan night prayer (tarawih) on the night of the festival

Question:
He says: Honorable Shaykh, may Allah grant you success. The imam prayed two or three units of the Ramadan night prayer (tarawih) on the night of the festival before the news arrived that it was the festival. When the news came, he stood up and led the congregation in the odd-numbered prayer (witr). Is his action valid?

Answer:
This is good, yes, this is good. As long as he had prayed part of the prayer with them and the news arrived, he stands up and prays the odd-numbered prayer (witr).
It is permissible for them to pray the witr in congregation occasionally, without making it a regular habit. If they gather at times, it is permissible for them to pray the witr in congregation. They used to pray some voluntary prayers in congregation with the Prophet (peace and blessings be upon him), such as the story of Anas ibn Malik and his mother, where he said, "I stood up and prayed a voluntary prayer in the house of 'Utbah ibn Malik in congregation." So, it is permissible to pray in congregation for a voluntary prayer at times, yes, without making it a regular habit, yes.
