Ali ibn Abi Talib (May Allah be pleased with him) entered the Masjid once, and in it was a man scaring the people [with his admonitions and reminders].

So he asked: What is this?

They said: A man reminding the people.

So he said: That is not a man who is reminding people, rather he is one who is saying to them: I am so-and-so, [and you should] know me.

Then he called him and asked: Do you know [how differentiate between] the Nasikh and the Mansoukh (i.e. the abrogated and what abrogated it)?

The man said: No

So Ali (May Allah be pleased with him) said to him: Then leave our Masjid and do not remind the [people] in it.

دخل علي بن أبي طالب المسجد فإذا برجل يخوف الناس فقال : ما هذا ؟ 
فقالوا : رجل يذّكر الناس . 
فقال : ليس برجل يذكر الناس ولكنه يقول : أنا فلان بن فلان فاعرفوني، فأرسل إليه فقال : اتعرف الناسخ من المنسوخ ؟ 
فقال : لا .
قال : فاخرج من مسجدنا ولا تذّكر فيه
