Part 13: Just makin' it up as you go along.
The laws, rules and cultural mores that a billion Muslims worldwide are expected to live their lives to are, contrary to popular belief, not drawn from the Qu'ran - not surprising for such a disjointed, tedious work mainly concerned with describing the Hell that awaits unbelievers and the intricate details of inconsequential seventh century battles.
Most of what we consider indicative of the Islamic lifestyle comes from the "Hadith", a collection of oral traditions believed by Muslism to convey the sayings and actions of their prophet, the story about how the holy book was put together, and the adventures of Muhammed's own scooby gang of supporters, all transmitted through a medieval version of Chinese whispers. The man responsible for compiling most of them, Bukhari, died 238 years after Muhammed - and Bukhari's Hadith are considered to be among the most reliable and honest!
You'd expect such compilations to be deeply flawed - and indeed it is, and on a scale that might astonish people. Consider that of the three hundred thousand oral traditions Bukhari collected, he alone declared that two-thirds of that were entirely unsupported - in other words, bullshit. Further culling reduced the total of "reasonable" Hadith down to 10,000 - and, as much as Muslims might like to believe, it's entirely likely 99% of those remaining are just as ridiculous.
According to some scholars, such as Ignaz Goldzhier most of the Hadith are blatant plagarisations of earlier religious works - Jewish, Christians, Zoroastrian, Hellenic philosophy, some stuff from as far away as India and, surprise, surprise, a "word-for-word reproduction of the Lord's prayer." Even Islamic scholars would later have to characterise some Hadith into categories such as "lies told for material gain" and "lies told for ideological advantage".

Most Muslims are unfamiliar with the guts of the Hadith (and indeed, the Qu'ran itself) so reading the things for the first time can often be a confronting experience. (I once had an Afghan housemate who swore blind that the requirement for women to wear hijabs was in the Qu'ran. Nope - the Hadith.) But they should not be dismayed - for there is lots of cool and, yes, hilarious stuff in there. Along with some truly mindboggling pieces of filth.
Firstly. Jinn. They're in there, and in a big way. For those who don't know, Jinn are a pre-Islamic Arab pagan concept that managed to find itself grandfathered into Islam, uneasily sharing space with the Persian concept of angels and the Greek demons in Islam. Muslims believe that Jinn, like angels, were created by God though, unlike angels, Jinn have free will. And they are made of smoke. Iblis, the big-bad of Islam, was a Jinn who refused God's demand to give in to idolatry and worship Adam. Bad man, standing up for God's own rules and all.
Muhammed was a big believer in Jinn. Those nasty smoke demons could be found in the toilet, in your nose and in the bodies of your enemies. Despite what Disney tells us, they were very rarely found in lamps, and never sounded like Robin Williams.

Other stuff you may have missed:
So there you have it. God's final and most perfect prophet was a ginger-haired paedophile. Believe the Hadith, and you'll believe just about anything.
Then again, maybe it shows that South Park is right after all.

Gingers are evil!
