Islamic military jurisprudence - WikipediaThe word jihad appears frequently in the Quran with and without military connotations,  often in the idiomatic expression "striving in the path of God al-jihad fi sabil Allah ". Jihad is sometimes referred to as the sixth pillar of Islam , though this designation is not commonly recognized. The term jihad is often rendered in English as "Holy War",    although this translation is controversial. In Modern Standard Arabic , the term jihad is used for a struggle for causes, both religious and secular. The Hans Wehr Dictionary of Modern Written Arabic defines the term as "fight, battle; jihad, holy war against the infidels, as a religious duty ".
