Jihadism, in Islam, shares several 'family resemblances' with other religious fundamentalist movements. One of these noteworthy traits is militance against secularism and non-fundamentalist belief. While traditional scholars interpret jihad (literally 'a struggle') primarily as spiritual battle and secondarily as physical warfare, jihadists interpret the term as global 'holy war,' and some extremists encourage unrestricted tactics such as suicide bombing and targeting non-combatants. Although traditional Sunni Islam has, for centuries, favored scriptural exegesis based on taqlid (imitation or acceptance of prior jurists), jihadists use ijtihad (innovation or independent judicial reasoning) to re-interpret the Qur'an based on their perception of the world today. Ijtihad, however, appears to be re-emerging as a tool for moderate Muslims as well, who argue for an interpretation of the Qur'an that endorses peaceful coexistence with non-Muslims and advocates other humanitarian values.
