The word(s) "christians" appears 83 time(s) in 79 verse(s) in Quran in Mohsin Khan translation.

(71) And they divided not till after knowledge had come to them, through (selfish) transgression between themselves. And had it not been for a Word that went forth before from your Lord for an appointed term, the matter would have been settled between them. And verily, those who were made to inherit the Scripture [i.e. the Taurah (Torah) and the Injeel (Gospel)] after them (i.e. Jews and christians) are in grave doubt concerning it (i.e. Allah's true religion - Islam or the Qur'an).

(72) Has not the time come for the hearts of those who believe (in the Oneness of Allah - Islamic Monotheism) to be affected by Allah's Reminder (this Qur'an), and that which has been revealed of the truth, lest they become as those who received the Scripture [the Taurat (Torah) and the Injeel (Gospel)] before (i.e. Jews and christians), and the term was prolonged for them and so their hearts were hardened? And many of them were Fasiqun (the rebellious, the disobedient to Allah).

(73) O you who believe [in Musa (Moses) (i.e. Jews) and 'Îsa (Jesus) (i.e. christians)]! Fear Allah, and believe in His Messenger (Muhammad صلى الله عليه وسلم), He will give you a double portion of His Mercy, and He will give you a light by which you shall walk (straight). And He will forgive you. And Allah is Oft-Forgiving, Most Merciful.

(74) So that the people of the Scripture (Jews and christians) may know that they have no power whatsoever over the Grace of Allah, and that (His) Grace is (entirely) in His Hand to bestow it on whomsoever He wills. And Allah is the Owner of Great Bounty.

(75) And We have set none but angels as guardians of the Fire. And We have fixed their number (19) only as a trial for the disbelievers, in order that the people of the Scripture (Jews and christians) may arrive at a certainty [that this Qur'an is the truth as it agrees with their Books regarding the number (19) which is written in the Taurat (Torah) and the Injeel (Gospel)] and that the believers may increase in Faith (as this Qur'an is the truth), and that no doubt may be left for the people of the Scripture and the believers, and that those in whose hearts is a disease (of hypocrisy) and the disbelievers may say: "What Allah intends by this (curious) example ?" Thus Allah leads astray whom He wills and guides whom He wills. And none can know the hosts of your Lord but He. And this (Hell) is nothing else than a (warning) reminder to mankind.

(76) Some faces, that Day will be humiliated (in the Hell-fire, i.e. the faces of all disbelievers, Jews and christians).

(77) Those who disbelieve from among the people of the Scripture (Jews and christians) and Al-Mushrikun, were not going to leave (their disbelief) until there came to them clear evidence.

(78) And the people of the Scripture (Jews and christians) differed not until after there came to them clear evidence (i.e. Prophet Muhammad صلى الله عليه وسلم and whatever was revealed to him).

(79) Verily, those who disbelieve (in the religion of Islam, the Qur'an and Prophet Muhammad صلى الله عليه وسلم) from among the people of the Scripture (Jews and christians) and Al-Mushrikun will abide in the Fire of Hell. They are the worst of creatures.
