@Jihad Mohammad Hyjazie,
Firstly, let me give you some context. I consider myself to be very open minded -- one of my hobbies is to explore and collect points of view -- I also love seeing how other people worship -- I have been to many different congregations & religious ceremonies -- I really love people -- we are all so silly and wonderful & amazing. I also have a bias for religions that have a built-in sense of humour & I think that a lot of problems in the world come from people taking their world, themselves, etc way too solemnly. I also believe that everyone has certain inalienable rights that aren't given by our governments. I also believe that one of those inalienable rights is the right to religion; religion I believe is an integral part to humanity, it provides some essential meat. I also believe that ideas and thoughts are different than acts...thoughts & ideas shouldn't be illegal or punished, but acts should be. I used to think that all ideas are equal, but I'm seeing that not all ideas (and that includes systems of governance, countries, economic methods, etc) are equal, some ideas work better than others, but that countries have sovereignty and ability of freedom of thought & ideas are a part of our human inalienable rights. Whew!
So, good thing that there is a bounty of historical information on Mohammad. Following is a non-exhaustive list
In a mere 10 years of time, Mohammad commanded or led some 65 military campaigns
When Mohammad conquered Mecca, he ran across 2 slave girls singing what was interpreted as a satirical song aboot Mohammad.
How did he deal with this? He asked to warriors to murder them. When the girls tried escaping, one of the warriors ran down
the girls and trampled them to death with his horse. Mohammad then had the owner of the slave girls put to death.
After he conquered Mecca, his old scribe who was responsible for copying down Mohammad's utterances from Allah (who did a
kind of shorthand -- ferexample, when Mohammad would describe Allah the all-knowing & the All-Graceful he would write Allah the all-merciful & compassionate) noticed that after a while, Mohammad would change his utterances to what he the scribe had been writing. The scribe reasoned that if Mohammad were getting these utterances from Allah himself, Allah wouldn't change the wording and Mohammad would know the original wording. So the scribe ended up leaving Islam and going back to the religion of his fathers. Once Mohammad got back into Mecca, he made a hit list of those who must be killed. Guess one person who was on the hit list? The scribe hid with his brother or brother-in-law until things died down. His brother/brother-in-law then begged for mercy from Mohammad. After much pleading & Mohammad silence, Mohammad said that the scribe is forgiven. When he left the room Mohammad turned on his followers, very angry, asking them why they didn't cut the brother/brother-in-law down, why didn't you cut off his head? One of his men said that they weren't given orders to cut off his head. Mohammad replied that they don't need a sign from him to cut off the head of somebody who is a critic of mine*
In Medina, before Mohammad took Mecca, there were some poets who objected to Mohammad's way of rewarding those who were
faithful to him (by taking people out on raids on camel caravans from Mecca to Syria & murdering a few people & stealing their loot). One of these poets was the daughter of Marwan who had 5 children. One of Mohammad's warriors went to her home, taking a baby and murdered the daughter. In the morning the warrior was afraid that he had done this without explicit orders from Mohammad; upon meeting with Mohammad, Mohammad said that the world will no more care aboot this woman than it cares aboot two goats butting their heads together.
In the Battle of Badr Allah tells Mohammad It behooveth not a prophet that he should have captives until he hath greatly
slaughtered in the land
Mohammad declared that Jews are a race without understanding...transformed into apes and swine...Evil indeed are their
works...
When Mohammad attacked the Jewish Banu Quaraiza and they surrendered, all the men were beheaded, the women and children taken
as slaves, and the property distributed as booty.
A study was done with a big sample size (some 10,000 people in 10 different countries) looking at the odds of scapegoating
(which is positively correlated with dogmatism, inflexibility of belief & commitment to violence); they broke up the groups among Catholics, Protestants, Orthodox, Other, Christians, Jews, Hindus, Buddhists, Muslims, Non-religious, Atheists & Agnostics. The groups with the highest potential to scapegoat were the Catholics, Orthodox & Atheists. The groups with the lowest were the Buddhists, Hindus & Muslims. There's a lot of nuance. There's even been studies looking at scapegoating but to see if things like prayer & church attendance affect it...but that's enough for now, I think :3
So I don't think that this historical information on Mohammad means that Islam is wrong or evil...I believe religions are like pretty much like every other tool of humanity -- they can be used for both good and evil, right and wrong. The above historicity of Mohammad shows that what ISIL/DAESH/VZTP is doing isn't different from what Mohammad believed and acted like. & I understand how powerful beliefs can be and in-group cohesion.
*This illuminates the strange conversation between a reporter and one of the Charlie Hebdo murderers, Cherif Kouachi, he said
"We are not killers. We are defenders of the prophet, we don’t kill women. We kill no one. We defend the prophet. If someone offends the prophet then there is no problem, we can kill him. We don’t kill women. We are not like you. You are the ones killing women and children in Syria, Iraq and Afghanistan. This isn’t us. We have an honour code in Islam."
