Chapter on Innovations, Personal Opinions and Analogies

10. Muhammad ibn abu ‘Abdallah has narrated in a marfu’ manner from Yunus ibn ’Abd al-Rahman who has said the following. “I asked (Imam) abu al-Hassan the First, ‘How would I prove that Allah is one?’” The Imam replied, “O Yunus, do not be an innovator. One who depends on his personal opinion he is destroyed. One who abandons the members of the family of his prophet, goes stray. Whoever abandons the book of Allah and the words of His prophet he becomes an unbeliever.”
