The word ‘Islam’ appears in the Quran in 8 places
Word form ‘Al-Islam’
3:19 Indeed Ad-Deen (i.e the System of Life) approved by Allah is Al-Islam (Submission to His Laws and Commands). The people of the Scripture differed for nothing but selfish envy among themselves, after the Knowledge has come to them. One who rejects Allah’s Revelations will find that His Law of Requital is swift in reckoning.
3:85 Whoever seeks as Deen (i.e. a System of Life) (anything) other than Al-Islam, it will not be taken from him with approbation, and he will be a loser (in the long run in this world as well as) in the Hereafter.
5:3 Forbidden for you (for dietary consumption) are:
– Any Animal that dies of itself.
– The flesh of swine.
– And anything (not just meat) that has been dedicated to any other than Allah (such as an idol, grave or saint).
– Any Animal that has been strangled to death; Beaten to death; – Dies by falling from height; Gored to death by horns.
– Animal eaten by a wild animal unless you are able to slaughter it while it is still alive.
-That which is sacrificed on altars (devotional stones or blocks in shrines considered sacred).
Also forbidden is dividing the meat through raffling and games of chance. This Day, the rejecting opponents have given up the hope of eradicating your DEEN, System of Life. Clear distinction in matters of the Lawful and the Unlawful draws a tangible line between their ways and your way. Fear them not but fear Me. This Day, I have perfected your Law /DEEN for you, completed My favor upon you, and chosen for you Al-Islam as the System of Life.
In the above verse (5:3), after giving some rules and laws about dietary consumption, Allah says that He has perfected the Islamic Law [the word Deen seems here to have been used to mean Law, as it has been used to mean law in 12:6, since it comes after mentioning some laws about dietary consumption. The second occurrence of the word Deen in 5:3 seems to have been used to mean 'the System of Life', as the context shows]
61:6-7 And Jesus, son of Mary said, “O Children of Israel! Behold, I am a Messenger of Allah unto you. I confirm the Divine Origin of the Torah, and give you the glad news of a Messenger to come after me whose name shall be Ahmad (the Praised One.”) But when he has come unto them with the self-evident Truth, the People of the Scripture say, “It is obviously a magical lie.” And who does greater wrong than he who invents a lie against Allah when he is invited to Al-Islam? But Allah does not guide the people who are Zalimeen (, who do not put things in their right perspective).

6:125 Therefore (for) whomsoever Allah intends that He would guide him aright [according to His Laws such as given in 2:2, 3:101, 7:52, 13:27, 27:2, 27:77, 31:3, 41:44] He expands his breast for Al-Islam, and (for) whomsoever He intends that He should cause him to err [according to His Laws such as given in 2:26, 9:115, 14:27, 40:34, 40:69-74, 45:23], He makes his breast strait and narrow as though he were ascending upwards; thus does Allah lay malediction/uncleanness on those who do not believe.
39:22 If Allah renders one’s breast open to Al-Islam he will be following a Light from his Sustainer. Hence, those whose hearts are hardened against Allah’s Reminder only harm themselves. They are most obviously lost in error.

49:17 Some people act as if they are doing you a favor by embracing Islam (or submission to Allah’s Commands). Say, “Deem not that your Islam (or your submission to Allah’s Commands) is a favor upon me. Nay, it is Allah Who bestows a favor upon you as He has led you to the Faith, if you be true and sincere.”
Word form ‘Islamihim’
9:74 (The hypocrites) swear by Allah that they have said nothing wrong. Yet they most certainly have uttered a word of disbelief (9:61-62). And have denied the Truth after their Islam (or professing their surrender to Allah). They were aiming at something beyond their reach (attaining inner peace without sincerity to the Divine Guidance). And they could find no fault in the Divine System except that Allah has enriched them and caused His Messenger to enrich them out of His Bounty. Hence, it will be good for them if they repent and correct themselves. But if they still turn away, Allah will cause them to suffer grievous retribution in this world and in the life to come. And they will have no protector or helper in the earth.
