Here are quotes of some verse from the Qur'an, the holy book 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!”
