"Remember Allah inspired the angels: I am with you. Give firmness to the believers. I will instill terror into the hearts of the unbelievers: you smite them above their necks and smite all their fingertips off of them." (Koran, 8:12)
What would it take for you to accept the possibility that people mean what they say and know more about what they say than you tell me you know what they say? Why should I believe you rather than the commandments of their religion and 1,500 years of history?
How is it that I keep failing to recognize your version of what I'm saying? Millions of people call themselves "Christians" but do not adhere to the letter of the Bible while others do--they are called fundamentalists. Likewise not all Muslims adhere to a literal translation of the Koran, while others--called "FUNDAMENTALISTS"--do. How is it that you can't grasp the concept that religions evolve into various sects that follow their sacred writings in varying degrees and in some cases, such as Protestant liberals, virtually not at all. Hence Catholics, Lutherans, Presbyterians, Methodists, Mormons, Unitarians etc.
In Islam varying interpretations have led to Ahmaydia, Alawi, Druze,Ismali,Nation of Islam, Salafy, Shia, New Sufi,and Wahhabi Movements. Clearly when it comes to doctrine, Islam is no more monolithic than Christianity. Some of these sects take every word of the Koran literally while others have more nuanced interpretations. Perhaps Muhammad is rolloing over in his grave, but there it is.
