The position of the one praying regarding a preacher who calls to religious innovation (bid'ah) in his sermon

Question:
And peace, he asked Allah for the Lord of the worlds, and he was with a family with him, so they gathered, and his heart was calling to others, and I have that

Answer:
If you have knowledge. If you have knowledge and you attach yourself to the sermon with wisdom and gentleness, without any harshness or roughness. We attach to the sermon with good words and clear evidence, and if Allah wills, the truth will become clear. But if you do not have knowledge, then you report this preacher to the authority responsible for the mosques in order to remove him from the mosque. One who calls to religious innovations (bid'ah) is not fit to be an imam or a preacher. And this country, praise be to Allah, does not approve of these matters, and those responsible for its administration remove this one who calls to religious innovations (bid'ah) and put in his place someone better than him.
The result is that silence is not permissible. If you are able to follow up and comment, then follow up and comment. If you are not able, then report your matter to the nearest office of the Ministry of Awqaf to remove this preacher.
