The word(s) "monotheism" appears 283 time(s) in 267 verse(s) in Quran in Mohsin Khan translation.

(71) How much would those who disbelieved wish that they had been Muslims [those who have submitted themselves to Allah's Will in Islam i.e. Islamic monotheism - this will be on the Day of Resurrection when they will see the disbelievers going to Hell and the Muslims going to Paradise].

(72) Therefore proclaim openly (Allah's Message - Islamic monotheism) that which you are commanded, and turn away from Al-Mushrikun (polytheists, idolaters, and disbelievers - See V.2:105).

(73) And Allah puts forward (another) example of two men, one of them dumb, who has no power over anything (disbeliever), and he is a burden on his master; whichever way he directs him, he brings no good. Is such a man equal to one (believer in the Islamic monotheism) who commands justice, and is himself on the Straight Path?

(74) Verily, Allah enjoins Al-'Adl (i.e. justice and worshipping none but Allah Alone - Islamic monotheism) and Al-Ihsan [i.e. to be patient in performing your duties to Allah, totally for Allah's sake and in accordance with the Sunnah (legal ways) of the Prophet صلى الله عليه وسلم in a perfect manner], and giving (help) to kith and kin (i.e. all that Allah has ordered you to give them e.g., wealth, visiting, looking after them, or any other kind of help), and forbids Al-Fahsha' (i.e all evil deeds, e.g. illegal sexual acts, disobedience of parents, polytheism, to tell lies, to give false witness, to kill a life without right), and Al-Munkar (i.e all that is prohibited by Islamic law: polytheism of every kind, disbelief and every kind of evil deeds), and Al-Baghy (i.e. all kinds of oppression). He admonishes you, that you may take heed.

(75) Whoever works righteousness - whether male or female - while he (or she) is a true believer (of Islamic monotheism) verily, to him We will give a good life (in this world with respect, contentment and lawful provision), and We shall pay them certainly a reward in proportion to the best of what they used to do (i.e. Paradise in the Hereafter).

(76) (He was) thankful for His (Allah's) Favours. He (Allah) chose him (as an intimate friend) and guided him to a Straight Path (Islamic monotheism - neither Judaism nor Christianity ).

(77) Then, We have sent the revelation to you (O Muhammad صلى الله عليه و سلم saying): "Follow the religion of Ibrahim (Abraham) Hanif (Islamic monotheism - to worship none but Allah) and he was not of the Mushrikun (polytheists, idolaters and disbelievers).

(78) And whoever desires the Hereafter and strives for it, with the necessary effort due for it (i.e. does righteous deeds of Allah's Obedience) while he is a believer (in the Oneness of Allah - Islamic monotheism) - then such are the ones whose striving shall be appreciated, (thanked and rewarded by Allah).

(79) And We have put coverings over their hearts lest they should understand it (the Qur'an), and in their ears deafness. And when you make mention of your Lord Alone [La ilaha illallah (none has the right to be worshipped but Allah) Islamic monotheism (توحيد الله)] in the Qur'an, they turn on their backs, fleeing in extreme dislike.

(80) And say to My slaves (i.e. the true believers of Islamic monotheism) that they should (only) say those words that are the best. (Because) Shaitan (Satan) verily, sows a state of conflict and disagreements among them. Surely, Shaitan (Satan) is to man a plain enemy.
