I have seen several posts where the Koran is quoted in regards to killing infidals. I have seen people come back with it is out of context but I have never seen it in context. Can someone please help me with that?
It depends on which passages you're talking about. Different verses were revealed in connection to different events that occurred when the early Muslim community was gaining its footing. What do you know about the beginning of Islam and the life of Muhammad (SAWS)? Being familiar with the gist of early Islamic history can help a lot if you're trying to understand the circumstances under which the religion was born.
I have also seen where innocents or those who believe in Allah only. If that is true then that would lead me to believe that anytime the Muslim world states it was wrong to kill innocents they are only referring to Muslims who were killed. I would like for that to be disproved as well.
Whether they're considered innocent or not doesn't matter. Targeting various types of noncombatants is expressly forbidden.
Narrated Anas ibn Malik: The Prophet said, "Go in Allah's name, trusting in Allah, and adhering to the religion of Allah's Apostle. do not kill a decrepit old man, or a young infant, or a child, or a woman; do not be dishonest about booty, but collect your spoils, do right and act well, for Allah loves those who do well." - Sunan Abu Dawud, Jihad, no. 2608
This was repeated by Abu Bakr (RA) when he addressed his soldiers:
"Do not kill a woman, a child, or an old man. Do not cut down a blossoming tree, do not destroy a building, and do not kill a sheep or camel, except for the purpose of eating it. Do not submerge or cut down a palm tree. Do not be excessive, and do not be cowardly."
The final thing that I have seen Koran scripture (I do not know if that is the correct term) state is alright to lie to your enemies (infidals) to save yourself and further your cause. Can you show me the context of this?
The Qur'an permits hiding your faith if your life is in danger. In a hadith, the Prophet (SAWS) said that dishonesty toward enemies during battle was permitted along with dishonesty used to bring about reconciliation between quarreling people as well as between husbands and wives.
I am not trying to attack the religion I am trying to understand it. I have seen posts state that the Christian Religion also states many of the same things. They then quote the Old Testament. I quickly point out the flaw because the Christian religious practices are based in the New Testament.
One last thing: Are there different denominations in the Muslim Religion?
Yes. The main divisions are Sunni and Shi'ite; each of these is divided into various schools of jurisprudence and theology.
