The word(s) "islam" appears 422 time(s) in 367 verse(s) in Quran in Mohsin Khan translation.

(91) And it is not (proper) for the believers to go out to fight (Jihad ) all together. Of every troop of them, a party only should go forth, that they (who are left behind) may get instructions in (islamic) religion, and that they may warn their people when they return to them, so that they may beware (of evil).

(92) To Him is the return of all of you. The Promise of Allah is true. It is He Who begins the creation and then will repeat it, that He may reward with justice those who believed (in the Oneness of Allah - islamic Monotheism) and did deeds of righteousness. But those who disbelieved will have a drink of boiling fluids and painful torment because they used to disbelieve.

(93) Mankind were but one community (i.e. on one religion - islamic Monotheism), then they differed (later); and had not it been for a Word that went forth before from your Lord, it would have been settled between them regarding what they differed .

(94) Allah calls to the Home of Peace (i.e. Paradise, by accepting Allah's religion of islamic Monotheism and by doing righteous good deeds and abstaining from polytheism and evil deeds) and guides whom He wills to the Straight Path.

(95) Say: "In the Bounty of Allah, and in His Mercy (i.e. islam and the Qur'an); - therein let them rejoice." That is better than what (the wealth) they amass.

(96) Those who believed (in the Oneness of Allah - islamic Monotheism), and used to fear Allah much (by abstaining from evil deeds and sins and by doing righteous deeds).

(97) "But if you turn away [from accepting my doctrine of islamic Monotheism, i.e. to worship none but Allah], then no reward have I asked of you; my reward is only from Allah, and I have been commanded to be of the Muslims (i.e. those who submit to Allah's Will)."

(98) Say (O Muhammad صلى الله عليه وسلم): "O you mankind! If you are in doubt as to my religion (islam), then (know that) I will never worship those whom you worship besides Allah. But I worship Allah Who causes you to die, and I am commanded to be one of the believers.

(99) "And (it is revealed to me): Direct your face (O Muhammad صلى الله عليه وسلم) entirely towards the religion Hanif (islamic Monotheism, i.e. to worship none but Allah Alone), and never be one of the Mushrikun (those who ascribe partners to Allah, polytheists, idolaters, disbelievers in the Oneness of Allah, and those who worship others along with Allah).

(100) If then they answer you not, know then that it [the Revelation (this Qur'an)] is sent down with the Knowledge of Allah and that La ilaha illa Huwa: (none has the right to be worshipped but He)! Will you then be Muslims (those who submit in islam)?
