Refuting the claim that congregational night prayer is an innovation

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling on praying the night prayer in congregation in the mosque? And what is the evidence for this, so that I may argue with the one who says it is an innovation?

Answer:
Do not argue with him; he is ignorant, and an ignorant person can never be convinced, no matter what you do. He is an ignorant person who claims to be a scholar. If he admitted he was ignorant, the matter would be easy, but this is an ignorant person who claims to be a scholar, and you will never be able to defeat him in argument. I think al-Shafi'i said, "I argued with the scholars and defeated them, except for the ignorant one; I argued with him and when I was unable to defeat him..." or something to that effect? Never argue with an ignorant person. Yes, first explain the matter to him. Explain it to him at the outset; if he accepts it, fine, otherwise leave him alone. Yes.
