Is it farther or further?
partisans or irregulars in the Middle East, from Arabic plural of fedai "devotee, zealot, one who risks life for a cause," from Persian fidai.
a term used in Islamic cultures to describe a devotee of a religious or national group willing to engage in self-immolation to attain a group goal. The term first appeared in the 11th-13th centuries in reference to the members of the Nizari Isma'ili sect of Assassins who would risk their lives to commit political murder, an assignment considered a religious duty. Though fida'iyyun (fedayeen) may have constituted a special body of "Assassins," accounts of their taking hashish as a stimulant are not supported by evidence
