As apocryphally attributed to Ghandi, "'I like your Christ, I do not like your Christians. Your Christians are so unlike your Christ.'"
I was raised a fundamentalist Christian, so I can quote the bible to you backward and forward. It contains horrible things and I personally know many people who do horrible things in their christian god's name.
I was never muslim, but I can google as well as you can and produce:
"And those who, when tyranny strikes them, they defend themselves, And the recompense of evil is punishment like it, but whoever forgives and amends, he shall have his reward from Allah; surely He does not love the unjust. And whoever avenges himself after having been wronged - those have not upon them any cause [for blame]. The way (of blame) is only against those who oppress mankind, and wrongfully rebel in the earth. For such there is a painful doom. (42:39-42)"
"'Whoever suffers an injury done to him and forgives (the person responsible), Allah will raise his status to a higher degree and remove one of his sins.'"
"Do not be people without minds of your own, saying that if others treat you well you will treat them well, and that if they do wrong you will do wrong. Instead, accustom yourselves to do good if people do good and not to do wrong if they do evil.'"
However you're completely and utterly missing the point. Which is the vast majority of Christians and Muslims are thankfully pretty bad at actually following their holy books faithfully, because both contain horrific things. I find fundamentalist of both religions abhorrent. I'm also rational and as such believe a religious test based on the most fundamentalist sect of any religion, as opposed to the actual real live human you're considering, is pretty ridiculous and you don't need any religion to figure that out. By the way, still wondering what possible explanation can explain why any religion that calls for stoning your disobedient sons is anything but barbaric? You can't "allegory" away that one!
I've been curious for the origin of Islam, and below is the top one of my google results.

Origin Of Islam
Origin of Islam: According to Secular History
The origin of Islam can be traced back to 7th century Saudi Arabia. Islam is thus the youngest of the great world religions. The prophet Muhammad (circa 570-632 A.D.) introduced Islam in 610 A.D. after experiencing what he claimed to be an angelic visitation. Muhammad dictated the Qur'an, the holy book of Islam, which Muslims believe to be the preexistent, perfect words of Allah.
Origin of Islam: According to Islam
The origin of Islam is generally accredited to the prophet Muhammad but to the devout Muslim, Islam began long before Muhammad ever walked the earth. The Qur'an was dictated by Muhammad but, according to the Qur'an, it did not originate with Muhammad. The Qur'an testifies of itself that it was given by God through the angel Gabriel to the prophet Muhammad. "This is a revelation from the Lord of the universe. The Honest Spirit (Gabriel) came down with it, to reveal it into your heart that you may be one of the warners, in a perfect Arabic tongue" (Sura 26:192-195). "Say, 'Anyone who opposes Gabriel should know that he has brought down this (the Qur'an) into your heart, in accordance with God's will, confirming previous scriptures, and providing guidance and good news for the believers'" (Sura 2:97).
The Origin of Islam: The "Previous Scriptures"
The origin of Islam is controversial. The "previous scriptures" mentioned above are the Hebrew Torah, the Psalms of David, and the Gospels of Jesus Christ (Sura 4:163; 5:44-48). The Qur'an accepts these books as divinely inspired and even encourages us to test its claims by these "previous scriptures." "If you have any doubt regarding what is revealed to you from your Lord, then ask those who read the previous scripture" (Sura 10:94). But this is where we run into a problem. The problem is that the Qur'an thoroughly contradicts the Torah, the Psalms, and the Gospels. For example, the Qur'an explicitly denies Jesus Christ's crucifixion (Sura 4:157-158) while all four Gospel accounts clearly portray Jesus Christ as crucified and resurrected.
