The distinctive idea here is not a belief in self-sacrifice—Islam, with its emphasis on the glory of dying in battle, has that idea in abundance. Nor is it the idea of a duty to serve others—Communist regimes were built on the idea that the individual exists only to serve the collective. Instead, it is the idea that each individual has a supreme and sacred value. Even Ayn Rand
declared this to be the idea from Christianity that most impressed her.
Islam has no corresponding idea. The news is constantly bringing us a story of some imam somewhere declaring it consistent with Islam for a man to beat his wife, and the rise of the Islamic State in Syria has provided us current examples of Islam sanctioning slavery, including the capture and systematic rape of sex slaves. This is a religion that is still very much in the “rights of the conqueror” mode, in which the strong do what they can and the weak suffer what they must.
Again, this goes back to the beginning. Consider the story, from one of the earliest Arab biographies of Mohammed, of
Asma bint Marwan, an Arab poet in Medinah who spoke out against the rise of Mohammed. According to legend, he asked his followers, “Who will rid me of the daughter of Marwan?” (His version of Henry II’s “Will no one rid me of this meddlesome priest?”) One of them took it on himself to sneak into her house and murder her in her sleep. There are questions about the authenticity of the story, but the fact that it was widely believed and reported indicates the example Mohammed set.
To be sure, this brutal attitude is partly because of the backwardness of some of the quasi-feudal societies that are majority-Muslim, where divisions of tribe and caste still dominate. But then again, Islam hasn’t done much to elevate those societies, despite having more than a thousand years to do so.
