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

(261) And as for Thamud, We showed and made clear to them the Path of Truth (islamic Monotheism) through Our Messenger, (i.e. showed them the way of success), but they preferred blindness to guidance; so the Sa'iqah (a destructive awful cry, torment, hit, a thunderbolt) of disgracing torment seized them because of what they used to earn.

(262) And who is better in speech than he who [says: "My Lord is Allah (believes in His Oneness)," and then stands firm (acts upon His Order), and] invites (men) to Allah's (islamic Monotheism), and does righteous deeds, and says: "I am one of the Muslims."

(263) He (Allah) has ordained for you the same religion (islamic Monotheism) which He ordained for Nuh (Noah), and that which We have revealed to you (O Muhammad صلى الله عليه و سلم), and that which We ordained for Ibrahim (Abraham), Musa (Moses) and 'Îsa (Jesus) saying you should establish religion (i.e. to do what it orders you to do practically), and make no divisions in it (religion) (i.e. various sects in religion). Intolerable for the Mushrikun, is that (islamic Monotheism) to which you (O Muhammad صلى الله عليه و سلم) call them. Allah chooses for Himself whom He wills, and guides unto Himself who turns to Him in repentance and in obedience.

(264) 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).

(265) So unto this (religion of islam alone and this Qur'an) then invite (people) (O Muhammad صلى الله عليه و سلم), and stand firm [on islamic Monotheism by performing all that is ordained by Allah (good deeds), and by abstaining from all that is forbidden by Allah (sins and evil deeds)], as you are commanded, and follow not their desires but say: "I believe in whatsoever Allah has sent down of the Book [all the holy Books, - this Qur'an and the Books of the old from the Taurat (Torah), or the Injeel (Gospel) or the Pages of Ibrahim (Abraham)] and I am commanded to do justice among you. Allah is our Lord and your Lord. For us our deeds and for you your deeds. There is no dispute between us and you. Allah will assemble us (all), and to Him is the final return."

(266) And those who dispute concerning Allah (His religion of islamic Monotheism with which Muhammad صلى الله عليه و سلم has been sent), after it has been accepted (by the people), of no use is their dispute before their Lord and on them is wrath, and for them will be a severe torment.

(267) You will see (on the Day of Resurrection), the Zalimun (polytheists and wrong-doers) fearful of that which they have earned, and it (Allah's Torment) will surely befall them. But those who believe (in the Oneness of Allah - islamic Monotheism) and do righteous deeds (will be) in the flowering meadows of the Gardens (Paradise). They shall have whatsoever they desire with their Lord. That is the supreme Grace, (Paradise).

(268) That is (the Paradise) whereof Allah gives glad tidings to His slaves who believe (in the Oneness of Allah - islamic Monotheism) and do righteous good deeds. Say (O Muhammad صلى الله عليه و سلم): "No reward do I ask of you for this except to be kind to me for my kinship with you." And whoever earns a good righteous deed, We shall give him an increase of good in respect thereof. Verily, Allah is Oft-Forgiving, Most Ready to appreciate (the deeds of those who are obedient to Him).

(269) Or say they: "He has invented a lie against Allah?" If Allah willed, He could have sealed up your heart (so that you forget all that you know of the Qur'an). And Allah wipes out falsehood, and establishes the truth (islam) by His Word (this Qur'an). Verily, He knows well what (secrets) are in the breasts (of mankind).

(270) And He answers (the invocation of) those who believe (in the Oneness of Allah - islamic Monotheism) and do righteous good deeds, and gives them increase of His Bounty. And as for the disbelievers, theirs will be a severe torment.
