2005 EURABIA: The Euro-Arab Axis (Islamic Conquest and Colonization of Europe)

Bat Ye’or: Jihad represents both a doctrine and a jurisdiction elaborated from three sources: the Koran, the Hadiths (words and deeds attributed to the Prophet Muhammad) and the biographies of the Prophet. Treatises on jihad have been written down and explained by the four founders of Islamic jurisprudence in the 8th and 9th centuries. Since then, they have represented an important part of Islamic legislation as jihad regulates the relationship between Muslims and non-Muslims according to Islamic law. According to the jihadic doctrine, the world is divided into two parts: Muslims and Infidels, the latter living in the dar al-harb, the land of war, because their land must be Islamized by peaceful means, or by war if they resist. Before attacking the Infidels, Muslims must first call them to convert; if they refuse, they are asked to pay a ransom; if they refuse again, Muslims have the duty to wage war on them. Truce is accepted on condition that the Infidels pay a regular ransom and put no obstacle to the spread of Islam in their own countries. There are other conditions also, like sending soldiers to fight for Islamic interests. A truce should not last more than 10 years, and it is allowed only when the Muslim ruler is weak. Otherwise, war against the Infidels is mandatory. The treatises on jihad establish with a meticulous precision the tactics and means to conduct war, the type of truces allowed and the treatment of prisoners of war: male, female and children, the division of the booty, the characters of the land of the Infidels that has become Islamized, the rules to govern the submitted Infidels and so on.
