In determining the bidah, people are generally divided into three categories:
Firstly, each of the things that are not available in the document is marked by a class of people, and in this case, they are all saying everything (even matters of Mu'amalah) as a bidat without special preference. To them, beyond the boundary of bidah, there is a wide range of distance.
(2) Those who are not inclined to believe in the innovation of all innovations in religion; Rather, they think that the rest of the new ones are in accordance with the law of belief. To them the limit of the bidah is very small.
Three: Those who have verified and selected only the actual bidah are called bidahs. They are middle-oriented and hypocritical.!
