Jihad
The sense of jihad as armed resistance was first used in the context of persecution faced by Muslims, as when Muhammad was at Mecca, when the community had two choices: emigration (hijra) or jihad. In Twelver Shia Islam, jihad is one of the ten Practices of the Religion. A person engaged in jihad is called a mujahid (plural: mujahideen). The term jihad is often rendered in English as "Holy War", although this translation is controversial. Today, the word jihad is often used without religious connotations, like the English crusade.
