Shaikhul Islaam Ibn Taymiyyah (rahimahullaah):
The legislated affairs of Islaam are nourishments of the hearts; and when the hearts are nourished with innovation, giving more virtue/excellence to the Sunan does not remain in them, so they come to be in the position of one who nourishes (himself) with filth. [Iqtidaa Siraat Al-Mustaqeem: 1/281]
Abdul Azeez Bin Rabee (rahimahullaah) said:
Ataa (rahimahullaah) was asked about something, so he said: ”I don’t know.” He (Abdul Azeez) said, (then) it was said to him (i.e. Ataa), ”Do you not speak about it with your own opinion?” He (Ataa) said: I feel shy of Allaah (The Mighty and Majestic) to be (slave and worshipper) in the earth with my opinion/s. [Reported by Imaam Daarimee in his sunan: 1/108]
Look at how Abu Usaamah -The Greenlane Khateeb of Desires– Started in 2002
The article in the above link is a detailed clarification of the falsehood of abu usaamah’s stances in the early days and his defence of the innovator Abul Hasan al-Maribi; also in the article Faaleh al Harbi is mentioned as one of the main defenders of the correct salafi positions, but the reader must be informed that Faaleh deviated thereafter and traversed the methodology of the extremist haddaadiyyah, so the scholars refuted him.
