The Attitude of Ascetics towards the Financial System in the Abbasid State during its Early Period

The present work does not aim at providing a historical presentation for asceticism and ascetics in the first three centuries of Hijrah ; it aims at dealing with an important ascetic issue namely the attitude of the ascetics towards the financial system of the Abbasids state in its early period esteeming from the Islamic theory : Cleary forbidden, Clearly permissible and suspiciously hateful
The research tries to answer an important question: why did the ascetics of the early Abbasids period forbid taking from the state finance while in the early Islamic period they permitted taking from the state money?
