According to the Lisān al-'Arab (Arabic dictionary by Ibn Manẓūr) al-Farouq refers to making a distinction between two subjects, and is a person who distinguishes between right and wrong.

[4] As, however, the morphophonology of the lexeme farūq is not Arabic, the word seems to be of Syro-Aramaic origin, e.g. pārōqā "Saviour" as for example pointed out by Robert M.

[5] According to historical Sunni sources, Muhammad entitled Umar ibn al-Khattab as al-Farooq.

"[8] Among historical Shia sources, there is a hadith attributed to Muhammad in which he entitled Ali ibn Abi Talib as al-Farooq.

[9] Abu Dhar al-Ghifari and Salman the Persian narrated some of this Hadithes [10] There are also some Shia sources that emphasized that the people of the book called Omar bin al-Khattab as al-Farooq.
