What the Qur'an Says About the Bible - The Qur'an's Respect for Christians
"Strongest among men in enmity to the believers wilt thou find the Jews and pagans; and nearest among them in love to the believers wilt thou find those who say 'We are Christians': because amongst these are men devoted to learning. And men who have renounced the world, and they are not arrogant." Sura 5:82. The footnote says this does not refer to everyone who calls himself a Christian, but sincere Christians.
Sura 2:62 says, "Those who believe (in the Qur'an). Those who follow the Jewish (scriptures), And the Sabians and the Christians,- any who believe in Allah and the Last Day, and work Righteousness, - on them shall be no fear, nor shall they grieve."
