The Messeenger of Allah صلى الله عليه وسلم also warned from the people of innovation.
He recited the verse [english meaning]
It is He Who has sent down to you (Muhammad صلى الله عليه وسلم ) the Book (this Qur'ân).
In it are Verses that are entirely clear, they are the foundations of the Book [and those are the Verses of Al-Ahkâm (commandments), Al-Farâ'id (obligatory duties) and Al-Hudud (legal laws for the punishment of thieves, adulterers)]; and others not entirely clear.
So as for those in whose hearts there is a deviation (from the truth) they follow that which is not entirely clear thereof, seeking Al-Fitnah (polytheism and trials), and seeking for its hidden meanings, but none knows its hidden meanings save Allâh.
And those who are firmly grounded in knowledge say: "We believe in it; the whole of it (clear and unclear Verses) are from our Lord."
And none receive admonition except men of understanding. .
[surah Ali Imran :7]
When the Messenger of Allaah صلى الله عليه وسلم recited this verse he said:
"If you see the one following that which is not clear from it then they are the ones whom Allah has mentioned, so beware of them." [al-Bukhari]
Allah has clarified that those who have deviance in their heart seek fitnah, evil and corruption:
"So as for those in whose hearts there is a deviation (from the truth) they follow that which is not entirely clear thereof, seeking Al-Fitnah"
You will not find an innovator except that he follows that which is not entirely clear whether it is from the Speech of Allah, the speech of the Messenger صلى الله عليه وسلم or from the speech of the scholars of the religion.
All of this is an attempt for him to misguide the people using these false doubts that he follows.
Unfortunately, this is the case both in the past and the present; you will not see a person who has deviated from the way of the people of the Sunnah and Jama'ah [ie body of Muslims unified upon the truth], except that he follows these doubts and strives to place corruption and evil doubts in the hearts of the people, sadly.
We ask Allaah to grant us , as well as you the ability to hold firmly to His Book, and to avoid innovation, doubts, and desires.
