In Reading the Koran (It is a version translated by NJ Dawood in plain modern English), especially the chronically latter verses, which come first in the Koran interestingly enough. The Koran talks a lot about fighting the disbelievers and/or how the disbelievers are going to meet a terrible fate in the afterworld, there is a verse intersting Sura 2 which says 'Fight for the sake of god those that fight against you, but do not attack them first. God does not love agressors', although further on the Koran says bloodshed is less worse than idolatry.
Sura 9 is interesting, 'A Declaration of Immunity from god and his apostle (Muhammad) to the idolaters (Non-Muslims) with whom you have made agreements'. further 'Proclaim a woeful punishment to the unbelievers, expect to those idolaters who honored their treaties with you in every detail and aided none against the you. With these keep faith, until their treaties have run their term. God loves the righteous.
The Koran confirms that Islam is a political ideology as well as a religion, there are a lot of laws in the Koran, such as those in inheritance, status of women, divorce, punishments. The Koran says about women they are worth half a man, those punishments and laws they meter out in places like Saudi Arabia, Iran and Taliban era Afghanistan are laid out in the Koran.
