Good question. Anybody?
I dont know if there are any islamic scholars on the board :)
Like studying satanism.
But I am curious as to the answer.
Having actually read the Quran...I’ll note this...there are only a handful of passages in the entire text (6,348 verses) that deal with law, period. So after Muhammad died...there was this flux-period. Around the year 900 (200 years after Muhammad had passed on)...there had been increasing arguments over interpretations of the Quran and law. So, the boys left in charge made their own interpretations and invented Sharia Law out of thin air. What you see today...is basically a 1,000 year old legal proceeding that fits with the period of 900 AD (one of the fifty-odd problems with a religion that cannot re-invent itself).
As for ‘rules’....always remember that the trilogy exists. A Muslim has to obey everything within the Quran, the Hadith, and Siri....along with the general rules of the Sharia Law business. All of this adds up to a ton of material and no one except scholars can ever cite or explain how each item (written 1,300 years ago) reflects upon life in today’s world. When some idiot journalist wants to tread upon any comment of the Quran....you need to raise your hand and ask if they actually read at least the Quran by itself, first page to the last page. Most will say no, and you can stop the discussion with the journalist right there on the spot.
Taqiyya.
