Context: "Jihad" is a song by the American thrash metal band Slayer which appears on their 2006 album "Christ Illusion".  The song portrays the imagined viewpoint of a terrorist who has participated in the September 11, 2001 attacks, concluding with spoken lyrics taken from words left behind by Mohamed Atta; Atta was named by the FBI as the "head suicide terrorist" of the first plane to crash into the World Trade Center.  "Jihad" was primarily written by guitarist Jeff Hanneman; the lyrics were co-authored with vocalist Tom Araya. Diabolus in Musica is the eighth studio album by American thrash metal band Slayer.  Released on June 9, 1998, it is the third studio album to feature drummer Paul Bostaph.  Although receiving mixed critical reviews, the album sold 46,000 copies in its first week to peak at number 31 on the "Billboard" 200.  Guitarist Jeff Hanneman wrote most of the album's content which has been described as Slayer's most experimental album.  It is the band's first studio album to be played mostly in C♯ tuning.

Lyrical themes explored on the album include religion, cultural deviance, death, insanity, war, and homicide. ESP Jeff Hanneman is an electric guitar model distributed by ESP for the late Jeff Hanneman of the thrash metal band Slayer.

Hanneman's own instruments (all modeled after his favorite Jackson Soloist the guitar used on most of Slayer's albums) have pure maple, not alder, bodies.  The ESP edition originally featured a Floyd Rose tremolo, which upset a large number of Slayer fans.  In response, ESP began offering the Kahler 2315.
