Sharia law doesn't do anything different than 10 commandments from the Torah, 10 Bill of rights from Magna Carta, Arabic metric system of 10's and the mathematical integers of 0-9. If anyone wants the first 10 amendments to the United States Constitution after 16 months first ratified.
Then there is Eastern philosophies and 5 percepts in Buddhism, 5 teachings of Taoism, 7 principles of Zen. I won't go into paganism and mythology.
anyway all combined do one thing, teach opposition to understanding life in real time. Everyone is trained since dawn of civilization to think two sides of any issue, problem, idea.
yin and yang, good and bad, good and evil, anything is possible, universe is always expanding, life will get better tomorrow. What isn't allowed to be discussed is why living never exceeds mutually balancing in one's ancestral time displaced never same form shaped since conceived.
they must always debate on the premise anything else is possible, but one operating system that works regardless which generation gap one arrives, or any other place universally present.
Reasonable doubt doesn't discover self evident results, it covers up the process keeping things eternally different adapting in the moment here. And it only does it from within this species each generation gap added changing population never duplicated an ancestor once.
Every citizen of every ideology will disagree with me. they will unite in calling me anti-social, a malcontent with humanity saving humans from their natural outcome of limited to adapting in the moment here where salvation arrives believing intellectual soul lives beyond the body navigating space timed apart now.
so the rhetorical question of the title's question is nothing but those believing in allah defending their human rights to deny now is eternity like any other religion has.
