He is wrong in praying night prayer in four Rakah. You should tell him that this is against the Sunnah according to the most authentic opinion and that if he prayed it 2×2 no one would say he was wrong but when praying it 4, a large number of scholars would disagree with him.

Yesterday we are praying tarawih following the imam.. After two rakahs he didn’t sit but he said allahuakbar and stood.. Then some people were saying subhanallah.. But after that also imam continues two more rakahs after that only he sit.. Is there any prayer like this… or the imam did mistake? This is the second time he did this. In this situation what we are supposed to do..
