Sh. Ṣāliḥ al-Fawzān Hafiẓahullāh: Reasons for deviation in ʿAqeedah are as follows:

• Ignorance of Deen

• Fanaticism towards beliefs of ancestors even if they’re false

• Blind-following men without proof

• Extremism in raising the rank of ʿAwliyā (righteous ones)

• Being heedless of Qurʾān and not pondering upon it

• Lack of Islamic education at home
