 In conclusion, whereas in Ihsâ’ al-‘ulûm (“The Enumeration of the Sciences”), al-Fârâbî deals with Muslim sciences such as theology (kalâm) and law (fiqh), the Ikhwân mainly stress religion. In the Rasâ’il, the usual distinction between philosophy/sciences (the rational or ‘aqliyya knowledge) and theology (the received or naqliyya knowledge), or between reason and faith is not valid as both are combined.
