Does Obama know this?
Do you mean, does he know of the different translations of the Holy Quran?
I doubt it.
IMHO None of our leaders, including the Bush family has ever read a true copy of the Holy Quran.
Two reasons for this.
1. If you were going to give a gift of a Holy Quran to a person of power or wealth, what one would you give him?
The best looking "presentation" Holy Quran sold in USA bookstores is a green leather bound one for over a hundred bucks. Makes a great gift.
The left side of every page is in Arabic, the right in English.
2. If you were an Arabic reading Muslim, and you knew the different translations, you would give any infidel the modified for infidels one to make them think Islam was a "religion of peace".
I asked a non Muslim friend who reads Arabic to go to a bookstore with me and read the Arabic side vs the English one.
I selected a sura, "Spoils of War", as I know that is one substantially modified for USA consumption.
He looked in shock as he read them.
He commented that they might as well be two different books.
On the Arabic side, The title is "spoils of War".
It details how Allah will rain fire upon the infidels.
It explains how the true believers who fight in the jihad will receive a greater amount of the spoils and those true believers who remained home and did not fight will receive a lesser portion.
The English side, as well as most modern translations in the last 20 to 40 years, is titled, "Victory".
It just says that Allah will shower the true believers with "great acquisitions".
It never says anything about jihad or where those "acquisitions" comes from.
IMHO most infidels (Americans, westerners in general, etc., who have taken the time to read the Holy Quran have had the wool pulled over their eyes.
These modern translations are Taqiyya.
Lying to advance the cause of Islam.
Anyone who reads them would believe Islam is a "religion of peace".
I'm just lucky to have read a translation from the 1800s that tells it like it is.
When I bought a modern one, I was shocked to see the differences.
I started searching the internet for true translations.
Some are on http://www.gutenberg.org in the religion section.
IMHO our leaders have been unknowingly basing our government policy on a complete lie for the last 40 years or so.
I would say this definitely includes Clinton and the Bushs, It probably includes Obama.
