The following slideshow (produced by Islam Tees) highlights the evils and danger of innovations and the people of innovation and desires, especially the heads of innovation and those who call to innovated beliefs, actions or principles in the religion, and also those who accompany them, aid them, praise them, defend them and work with them.

This is the reason why Salafis in particular pay attention to Bid’ah and warn against it (in all its forms), following in the footsteps of our beloved Prophet Muhammad (صلى الله عليه وسلم) who used to mention and highlight this in his sermons (beginning with Khutbah al-Hajah). Bid’ah is from the major causes of disunity and splitting in the Ummah. This is an established fact, borne witness to by Islamic history wherein sects appeared due to them innovating things (which they might have thought were good) into the Religion but which opposed the Sunnah and the Deen, refer to this post for further explanation:
