Mohammed knew that most people are terribly cowardly and stupid. That is why he promised two beautiful women to every courageous warrior who dies in battle. This is the kind of language a soldier understands. When he believes that he will be welcomed in this manner in the afterlife, he will be willing to give his life, he will be enthusiastic about going to battle and not fear death. You may call this primitive and you may laugh about it, but it is based on deeper wisdom. A religion must speak a man's language.
Heinrich HimmlerLet us assume that the Turks in whose ranks Europeans were fighting as well, even in high positions, would have conquered Vienna and Europe in 1683 instead of having been forced to withdraw. If the Mohammedans would have gained the victory at the time and Islam would have swept victoriously over Europe, then the Christian churches would have been depoliticized. (...) For the Turks were religiously tolerant, they allowed each religion to continue to exist, provided it was no longer involved in politics - otherwise it was finished.
