 However, the reverse accusation is returned that their attackers are Munafiqun for abandoning the articles of Imaan especially that concerning belief in the 4 books which "Alians" believe and for adopting ibn Hazm's doctrine of Tahrif instead which Alians reject.The Alians have very similar beliefs and practices to the Alevis and along with Alevis are surviving examples of pre-Sunni Islam because the Alians are believed to be descendants of a member of the Banu Eli tribe who was called Abbas ibn Ali and Umm ul-Banin so their 12 imams (referring to 12 ministerial roles during the Alian Mass) has nothing to do with Twelver Shiism.They believe the Quran was compiled by an Alian ex-convert to Monophysitism from Zoroastrianism called Salman al-Farsi whom they hold in high esteem.
