Jihad (جهاد‎‎) is an Arabic word which literally means striving or struggling, especially with a praiseworthy aim. It can have many shades of meaning in an Islamic context, such as struggle against one's evil inclinations, or efforts toward the moral betterment of society. In classical Islamic law, the term refers to armed struggle against unbelievers, while modernist Islamic scholars generally equate military jihad with defensive warfare. In Sufi and pious circles, spiritual and moral jihad has been traditionally emphasized under the name of greater jihad. The term has gained additional attention in recent decades through its use by terrorist groups.
