The Ruling on Alerting Preachers to Doctrinal Innovations

Question:
He says: If some of the writers, or some of those who call to Islam, have doctrinal innovations (bid'ah), and some of them point them out, but others discourage them, saying that this causes the weakness of Islam and weakens the unity of Muslims against the disbelievers, and that it is better to leave these innovations alone because they do not affect the strength of the disbelievers.

Answer:
This is a false statement. The caller to Allah must be upright in himself, a role model; he must be a good role model in himself. As for one who calls to Allah while he is not a role model, and he has innovations and newly invented matters, this is not permissible. We must warn the first type. Allah, Glorified and Exalted is He, said: He will warn against the innovations; otherwise, he would not be a caller. If he remains silent about the innovations and does not warn against them, he is not a caller. He does not warn against them while he is practicing them. He must first avoid them for the sake of Allah, Mighty and Majestic, and then call to Allah.
