The word(s) "oneness" appears 187 time(s) in 175 verse(s) in Quran in Mohsin Khan translation.

(51) And make not your oaths a means of deception among yourselves, lest a foot should slip after being firmly planted, and you may have to taste the evil (punishment in this world) of having hindered (men) from the Path of Allah (i.e. Belief in the oneness of Allah and His Messenger, Muhammad صلى الله عليه و سلم), and yours will be a great torment (i.e. the Fire of Hell in the Hereafter).

(52) Verily, Ibrahim (Abraham) was an Ummah (a leader having all the good righteous qualities), or a nation, obedient to Allah, Hanif (i.e. to worship none but Allah), and he was not one of those who were Al-Mushrikun (polytheists, idolaters, disbelievers in the oneness of Allah, and those who joined partners with Allah).

(53) And if you punish (your enemy, O you believers in the oneness of Allah), then punish them with the like of that with which you were afflicted. But if you endure patiently, verily, it is better for As-Sabirun (the patient).

(54) Verily, this Qur'an guides to that which is most just and right and gives glad tidings to the believers (in the oneness of Allah and His Messenger, Muhammad صلى الله عليه و سلم), who work deeds of righteousness, that they shall have a great reward (Paradise).

(55) 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).

(56) [Musa (Moses)] said: "Verily, you know that these signs have been sent down by none but the Lord of the heavens and the earth (as clear evidence i.e. proofs of Allah's oneness and His Omnipotence.). And I think you are, indeed, O Fir'aun (Pharaoh) doomed to destruction (away from all good)!"

(57) (He has made it) straight to give warning (to the disbelievers) of a severe punishment from Him, and to give glad tidings to the believers (in the oneness of Allah - Islamic Monotheism), who do righteous deeds, that they shall have a fair reward (i.e. Paradise).

(58) And say: "The truth is from your Lord." Then whosoever wills, let him believe; and whosoever wills, let him disbelieve. Verily, We have prepared for the Zalimun (polytheists and wrong-doers.), a Fire whose walls will be surrounding them (disbelievers in the oneness of Allah). And if they ask for help (relief, water), they will be granted water like boiling oil, that will scald their faces. Terrible is the drink, and an evil Murtafaq (dwelling, resting place.)!

(59) And the Book (one's Record) will be placed (in the right hand for a believer in the oneness of Allah, and in the left hand for a disbeliever in the oneness of Allah), and you will see the Mujrimun (criminals, polytheists, sinners), fearful of that which is (recorded) therein. They will say: "Woe to us! What sort of Book is this that leaves neither a small thing nor a big thing, but has recorded it with numbers!" And they will find all that they did, placed before them, and your Lord treats no one with injustice.

(60) He said: "As for him (a disbeliever in the oneness of Allah) who does wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with a terrible torment (Hell).
