The Holy Prophet (s.a.w.s.) said: For the devil, the existence of one Faqeeh (jurisprudent) is more intolerable than the existence of a thousand worshippers.
Imam Sadiq (a.s.) said: When you notice that a learned man Aalim has indulged in the material worlds consider him a criminal against religion and do not trust or rely on him because every lover goes round the thing he loves.
The Holy Prophet (s.a.w.s.) said: God Almighty revealed to Dawood (a.s.): Do not make a worldly scholar a mediator between Me and you; that he may prevent you from loving Me because they are robbers lurking on My path. The least that I do about them is that I take back the sweetness of prayers from their hearts.
It is reported from the Holy Prophet (s.a.w.s.): So long as they are not inclined toward the material world, the religious scholars and jurisprudents are trustees of the Prophet. Being asked what inclination towards world meant, the Holy Prophet (s.a.w.s.) replied, Obedience to a ruler. So beware of them in the matter of your religion when they begin to obey a ruler
