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

(251) And the man who believed said: "O my people! Follow me, I will guide you to the way of right conduct [i.e. guide you to Allah's religion of islamic Monotheism with which Musa (Moses) has been sent].

(252) Verily, We will indeed make victorious Our Messengers and those who believe (in the Oneness of Allah - islamic Monotheism) in this world's life and on the Day when the witnesses will stand forth, (i.e. Day of Resurrection) -

(253) And not equal are the blind and those who see; nor are (equal) those who believe (in the Oneness of Allah - islamic Monotheism), and do righteous good deeds, and those who do evil. Little do you remember!

(254) And your Lord said: "Invoke Me, [i.e. believe in My Oneness (islamic Monotheism) and ask Me for anything] I will respond to your (invocation). Verily! Those who scorn My worship [i.e. do not invoke Me, and do not believe in My Oneness, (islamic Monotheism)] they will surely enter Hell in humiliation!"

(255) Say (O Muhammad صلى الله عليه وسلم): "I have been forbidden to worship those whom you worship besides Allah, since there have come to me evidence from my Lord; and I am commanded to submit (in islam) to the Lord of the 'Alamin (mankind, jinn and all that exists).

(256) See you not those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah? How are they turning away [from the truth, (i.e. islamic Monotheism to the falsehood (i.e. polytheism)]?

(257) Then their Faith (in islamic Monotheism) could not avail them when they saw Our punishment. (Like) this has been the way of Allah in dealing with His slaves. And there the disbelievers lost utterly (when Our Torment covered them).

(258) Giving glad tidings [of Paradise to the one who believes in the Oneness of Allah (i.e. islamic Monotheism) and fears Allah much (abstains from all kinds of sins and evil deeds) and loves Allah much (performing all kinds of good deeds which He has ordained)], and warning (of punishment in the Hell-Fire to the one who disbelieves in the Oneness of Allah), but most of them turn away, so they hear not.

(259) Say (O Muhammad صلى الله عليه وسلم): "I am only a human being like you. It is revealed to me that your Ilah (God) is One Ilah (God - Allah), therefore take Straight Path to Him (with true Faith - islamic Monotheism) and obedience to Him, and seek forgiveness of Him. And woe to Al-Mushrikun (the polytheists, idolaters, disbelievers in the Oneness of Allah).

(260) Truly, those who believe (in the Oneness of Allah, and in His Messenger Muhammad صلى الله عليه وسلم - islamic Monotheism) and do righteous good deeds, for them will be an endless reward that will never stop (i.e. Paradise).
