The word(s) "christian" appears 15 time(s) in 14 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) 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.

(12) 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.

(13) The Jews call 'Uzair a son of Allah, and the christians call Christ the son of Allah. That is a saying from their mouth; (in this) they but imitate what the unbelievers of old used to say. Allah's curse be on them: how they are deluded away from the Truth!

(14) Those who believe (in the Qur'an), those who follow the Jewish (scriptures), and the Sabians, christians, Magians, and Polytheists,- Allah will judge between them on the Day of Judgment: for Allah is witness of all things.
