The Epistle of the Eloquent Clarification Concerning the Refutation of Ibn Qutayba by Al-Qāḍī al-Nuʿmān b. Muḥammad (d. 363/974)
This book offers an early Shiite/Fatimid controversy against Sunnite scholars in matter of Islamic law. Al-Qadi al-Nu'man (d. 363/974) refutes Ibn Qutayba's (d. 276/889) argument according to which succinct legal formulas exempt civil servants from the need of long dissertations of jurists.
