An imam who prayed tarawih in four rak'ahs with one tashahhud, then four, then one, claiming it is from the Sunnah against the people of the mosque

Question:
May Allah reward you. Honorable Shaykh, a questioner says: The imam of a mosque in our area leads the tarawih prayer in Ramadan in four rak'ahs, then four rak'ahs, then one rak'ah, and then says the taslim. We have been told that this is not permissible, but he said that the Prophet (peace and blessings be upon him) prayed the night prayer in four rak'ahs, then four rak'ahs, then performed the witr.

Answer:
My brother, if you want to pray for yourself, do as you wish. But if you are praying for people, do not pray for them in a way that differs from the established practice. Follow the practice of the people in the area. Do not disrupt the Muslims. Do not become an imam. Do not become an imam. Pray for yourself, and it is between you and your Lord. Yes. As for you bringing your own independent legal reasoning and opinions and trying to impose them on the congregation, and going against the practice of the Muslims, this is not permissible. And if you do not desire the role of imam, do not lead people in prayer, burdening them, confusing them, and depriving them of the reward.
I hear that there are imams who close the mosques during the last ten nights. They close them after they have prayed tarawih. There is no threat or this is a deprivation. My brother, do not become an imam. Leave the role of imam to someone else. Do not deprive people. If you want to deprive yourself, do not deprive people. Yes.
