They maintain that any Muslim who professes such beliefs is an idolater whose idolatry is a worse kind than that of Pre-Islamic people who worshipped idols and planets.
In his book Kashful al-Shubuhat, Muhammad ibn Abdul Wahab called all Muslims, with the exception of his followers, idolaters about 24 times. Other labels he used to describe them were: heretics, idols' worshippers apostates, anti-divine unity, enemies of divine unity, Allah's enemies and perfidious Muslims in 20 different parts of the same book. His followers copied him in this practice.
It is essential to ask here if this doctrine was truly based on a consensus of learned scholars or is it a Wahabi bida' or corruption? Ibn Hazim, the well- known Sunni scholar, asserted that «a Muslim can not be called a heretic or a sinner on the bases of his opinions whether made in the form of a doctrine or a religious decree. After mentioning numerous religious scholars who endorsed this viewpoint he concluded that it was the consensus of all Companions who commented on it.»13
According to Ibn Taimia only the Khawarij judged other Muslims to be heretics on the bases of their sins and learned opinions or deductions.14 As such, the Wahabis have no precedent supporting this bida' except the infamous Khawarij.
