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

(161) And strive hard in Allah's Cause as you ought to strive (with sincerity and with all your efforts that His Name should be superior). He has chosen you (to convey His Message of islamic Monotheism to mankind by inviting them to His religion of islam), and has not laid upon you in religion any hardship: it is the religion of your father Ibrahim (Abraham) (islamic Monotheism). It is He (Allah) Who has named you Muslims both before and in this (the Qur'an), that the Messenger (Muhammad صلى الله عليه وسلم) may be a witness over you and you be witnesses over mankind! So perform As-Salat (Iqamat-as-Salat), give Zakat and hold fast to Allah [i.e. have confidence in Allah, and depend upon Him in all your affairs]. He is your Maula (Patron, Lord), what an Excellent Maula (Patron, Lord) and what an Excellent Helper!

(162) And indeed We sent Nuh (Noah) to his people, and he said: "O my people! Worship Allah! You have no other Ilah (God) but Him (islamic Monotheism). Will you not then be afraid (of Him i.e. of His punishment because of worshipping others besides Him)?"

(163) And verily this your religion (of islamic Monotheism) is one religion, and I am your Lord, so fear (keep your duty to) Me.

(164) Or say they: There is madness in him? Nay, but he brought them the truth [i.e. Tauhid: Worshipping Allah Alone in all aspects, the Qur'an and the religion of islam], but most of them (the disbelievers) are averse to the truth.

(165) And certainly, you (O Muhammad صلى الله عليه وسلم) call them to the Straight Path (true religion - islamic Monotheism).

(166) And verily, those who believe not in the Hereafter are indeed deviating far astray from the Path (true religion - islamic Monotheism).

(167) Nay, but We have brought them the truth (islamic Monotheism), and verily, they (disbelievers) are liars.

(168) (This is) a Surah (chapter of the Qur'an) which We have sent down and which We have enjoined, (ordained its laws); and in it We have revealed manifest Ayat (proofs, evidence, verses, lessons, signs, revelations - lawful and unlawful things, and set boundaries of islamic Religion), that you may remember.

(169) The adulterer-fornicator marries not but an adulteress-fornicatress or a Mushrikah, and the adulteress-fornicatress none marries her except an adulterer-fornicator or a Muskrik [and that means that the man who agrees to marry (have a sexual relation with) a Mushrikah (female polytheist, pagan or idolatress) or a prostitute, then surely he is either an adulterer-fornicator, or a Mushrik (polytheist, pagan or idolater). And the woman who agrees to marry (have a sexual relation with) a Mushrik (polytheist, pagan or idolater) or an adulterer-fornicator, then she is either a prostitute or a Mushrikah (female polytheist, pagan, or idolatress)]. Such a thing is forbidden to the believers (of islamic Monotheism).

(170) O you who believe! Follow not the footsteps of Shaitan (Satan). And whosoever follows the footsteps of Shaitan (Satan), then, verily he commands Al-Fahsha' [i.e. to commit indecency (illegal sexual intercourse)], and Al-Munkar [disbelief and polytheism (i.e. to do evil and wicked deeds; and to speak or to do what is forbidden in islam)]. And had it not been for the Grace of Allah and His Mercy on you, not one of you would ever have been pure from sins. But Allah purifies (guides to islam) whom He wills, and Allah is All-Hearer, All-Knower.
