Here are quotes of some verses in the Qur'an, the holy book of the religion of Islam.
Qur'an (4:89) - "They wish that you should disbelieve as they disbelieve, and then you would be equal; therefore take not to yourselves friends of them, until they emigrate in the way of God; then, if they turn their backs, take them, and slay them wherever you find them; take not to yourselves any one of them as friend or helper."
Qur'an (9:30) - "And the Jews say: Ezra is the son of Allah; and the Christians say: The Messiah is the son of Allah; these are the words of their mouths; they imitate the saying of those who disbelieved before; may Allah destroy them; how they are turned away!”
There are many verses in the Qur’an that call for jihad (struggle) and there are about 100 verses in the Qur'an that call for the destruction of Jews, Christians and non believers (infidels).
Don't you think Muslim fundamentalists use those verses in the Qur'an to inspire Muslims to kill non believers?
