All the major religions of that region inherited all their "science" from other cultures of the time.
You will find that the Arabic peoples (not to mention the Persians, Greeks and Hindus) were all using algebra long before Islam was a twinkle in Mohamud's eye.
But becasue Christianity didn't keep it's scientific inheritance in it's relious texts (if it kept much at all), does not mean that Islam is superior to it.
The only great Religions that have ever existed, are the anchient European ones, the Greek ones (inherited and addapted by the Romans), The Native American ones and Buddhism.
The Native American and Europeans Religons were good, since they required one to be at peace with nature. I like that. But they can't survive the people centric, Hate loving Religions.
The Greek Relions (Leading into the Roman ones) were good, Under this belief system Mankind's knowledge expanded exponentially. But there religions were too complex and libberal to survive simple, conservative religions.
Buddhism is good, because it's simple message is "be excellent to oneanother". Gods not included. ;-) People don't like being Execllent to oneanother though :-(
So we see a world slowing being dominated by Hate loving, simple, people centric, conservative religions... the simpler, more people centric, more conservative and more hate loving it is... the more popular it becomes.
In the west we have had the advantage of the "Enlightenment", were we managed to abstract out the core components of The dominant religion, and set up dedicated disciplins to cover it's role, rendering it essentially suplurfulous.
Religion became split into;
1. Politics
2. Science
3. Phylosophy
4. Spirituality
I rather like part 4. since we can now pick and choose a spirituality to best fit our lives. Organised Religion is, as I have pointed out, is now a waste of time.
