Are there types of bid'ah (religious innovations), and are there bid'ah that expel one from the religion?

Question:
May Allah reward you, Honorable Shaykh. This questioner asks: Are there types of bid'ah? And are there bid'ah that expel one from the religion?

Answer:
Yes, bid'ah are of different types, and some of them expel one from the religion, such as worshipping graves and calling for aid from the dead. These are bid'ah that expel one from the religion. Likewise, cursing Allah, cursing His Messenger, and cursing the Companions are bid'ah that expel one from the religion, because this is a denial of Allah and His Messenger, and a contradiction of the Book of Allah and the Sunnah of the Messenger of Allah. Yes.
