"the Arabs raped, murdered, and pillages southern Europe for 500 years,"
No, they didn't. First of all, they may even have been invited into Spain by one side in the conflict that was going on at the time - among xian factions, I might add. They did try to push into southern France, but were stopped, so remained confined to the Iberian peninsula (that's Basque country, Portugal, and Spain to you). After some at-sea raiding, they pretty much settled down and concentrated on government.
While there, they managed to rule pretty fairly and well, treating both xians and Jews quite tolerantly, and certainly being much nicer than the xians to the Jews. The rate of conversion to Islam in Spain was, in fact, rather high and it wasn't forced (although as with any religion, the one that's in power is always going to look more attractive to most people, and non-muslims did pay extra taxes, for example).
Also, during their reign they managed to elevate culture, education, medicine, philosophy, art, and literature among other fields to a truly admirable level with far-reaching effects and influences still surviving today, and not just in Spain. While they were there, xian Europe couldn't have cared less about islam, and it was only once the end of the Carolingian Empire left so many professional knights unemployed and needing military jobs that the xians' incursions on Spanish territory really picked up and started catching Europeans' imaginations (interesting, isn't it, that no united xian army rallied itself to go "free" the Iberian peninsula from the "muslim scourge;" the Spanish xians had to do that on their own).
All the other willfully ignorant claptrap you spewed (obviously you've never bothered to truly study history, just read badly-researched fundie propaganda) has already been addressed by ScienceIsGreen - and by the way, make up your mind: did the muslims "rape, murder, and pillage southern Europe" for 500 years or did they "over run [sic]" Spain for 300 years?
