Try to advise him, and give him evidences, if he doesn’t listen the sin is on him, try to find another masjid that follows quran and sunnah.

Our imam thinks all the Hadith of Bukhari, Muslim, Abu Dawud, Tirmidhi,Nasai,Ibn majah are saheeh. But I know only Bukhari and Muslim narrated all acceptable Hadith. Our imam celebrates “middle of the Shaban” “Eid-e- miladunnabi” etc. Now what should I do?
