Burying innovators in the graveyards of Ahl al-Sunnah

Praise be to Allah.

If the innovator is a kaafir because of his innovation, then it is not permissible to bury him in the Muslim graveyard, because the kaafir should be buried separately from the Muslims. But if he was not a kaafir because of his bid’ah, then there is nothing wrong with burying him with the Muslims. End quote.
