Unlike the religious sciences of jurisprudence and theology, medieval Arabic philosophy privileged the studies of Greek philosophical texts above Scripture. This openness to and acceptance of Greek philosophy is often associated with ¨liberal ¨and ¨rational¨ trends in the Arabic-Islamic philosophy. These so-called ¨liberal¨ trends in the ¨turath” (tradition/heritage) are incarnated in the political philosophies of Abu Nasr Al-Farabi (d.CE 950). Al-Farabi is a Muslim philosopher who combines two virtues, a loyalty to philosophy and faith in religion. In his language, Al-farabi perceived a significant through partial congruence between some Islamic virtues and the moralities that facilities the cultivation of reason. Besides, Al-farabi sought to confront, to relate and harmonize classical political philosophy with Islam. However, this paper attempts to decipher and draw a parallelism over several issues debated by Al-farabi between Islam and Al-farabi´s meanings and/or interpretations. In addition, this paper poses a pertinent question, ¨why does Al-farabi use or resort to the Greek philosophy? If thus, can we really consider Al-farabi´s produce as Neo-Platonism. Hence, the present paper tries to interrogate meantime provides an account of Al-farabi´s works, namely the Book of Religion, the Enumeration of the Sciences and the Theory of Emanation. Besides, this paper also investigates Al-farabi´s dualism between philosophy and religion as well as his language and style. Sub-theme: Finis Africae Trajectories
