If non Muslims are to understand Islam, then they must first understand the Qur'an-or Koran. The Koran is written in Arabic, but over 80% of Muslims are non-Arabic speakers. Islam means submission. Iihad means struggle, an individual's internal struggle against impure motivations and manifest behavior. Jihad is often translated-incorrectly according to some Muslims-as holy war against all infidels or people of all faiths except Islam.
The Koran for Christians seeks to help Christians further their understanding of Islam and moderate Muslims, and foster more positive interactions between the two faiths.
Much can be learned about Islam in a short time by understanding the Five Pillars of Islam, the Articles of Faith, and other basic tenets of a belief system held by millions.
