Imaam Ibnul Jawzi (rahimahullaah) stated:
When it is the case that addressing the (people) through exhortations is mostly (directed at) the common people, the ignorant story tellers found a way of reaching their goals. Then their bidah did not cease until the affair reached alarming proportions. So they brought about evil (affairs with regards to their) deeds, statements and goals.
