What is a Jihad?

1. Islamic campaign against nonbelievers: a campaign waged by Muslims in defense of the Islamic faith against people, organizations, or countries regarded as hostile to Islam
2. relentless campaign: a relentless campaign against somebody or something

Jihad is the Arabic for what can be variously translated as "struggle" or "effort," or "to strive," "to exert," "to fight," depending on the context. In the West, the word is generally understood to mean "holy war," and the terms are given, inaccurately, exclusively military connotations.

The Quran does call for "jihad" as a military struggle on behalf of Islam. But the Quran also refers to jihad as an internal, individual, spiritual struggle toward self-improvement, moral cleansing and intellectual effort. It is said that Prophet Muhammad considered the armed-struggle version of holy war "the little jihad," but considered the spiritual, individual version of holy war--the war within oneself--as "the great jihad."
