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

(141) You will see (on the Day of Resurrection), the Zalimun (polytheists and wrong-doers) fearful of that which they have earned, and it (Allah's Torment) will surely befall them. But those who believe (in the oneness of Allah - Islamic Monotheism) and do righteous deeds (will be) in the flowering meadows of the Gardens (Paradise). They shall have whatsoever they desire with their Lord. That is the supreme Grace, (Paradise).

(142) That is (the Paradise) whereof Allah gives glad tidings to His slaves who believe (in the oneness of Allah - Islamic Monotheism) and do righteous good deeds. Say (O Muhammad صلى الله عليه و سلم): "No reward do I ask of you for this except to be kind to me for my kinship with you." And whoever earns a good righteous deed, We shall give him an increase of good in respect thereof. Verily, Allah is Oft-Forgiving, Most Ready to appreciate (the deeds of those who are obedient to Him).

(143) And He answers (the invocation of) those who believe (in the oneness of Allah - Islamic Monotheism) and do righteous good deeds, and gives them increase of His Bounty. And as for the disbelievers, theirs will be a severe torment.

(144) So whatever you have been given is but (a passing) enjoyment for this worldly life, but that which is with Allah (Paradise) is better and more lasting for those who believe (in the oneness of Allah - Islamic Monotheism) and put their trust in their Lord (concerning all of their affairs).

(145) And you will see them brought forward to it (Hell) made humble by disgrace, (and) looking with stealthy glance. And those who believe will say: "Verily, the losers are they who lose themselves and their families on the Day of Resurrection. Verily, the Zalimun [i.e. Al-Kafirun (disbelievers in Allah, in His oneness and in His Messenger صلى الله عليه و سلم, polytheists, wrong-doers)] will be in a lasting torment. (Tafsir At-Tabari).

(146) (You) who believed in Our Ayat (proofs, verses, lessons, signs, revelations, etc.) and were Muslims (i.e. who submit totally to Allah's Will, and believe in the oneness of Allah - Islamic Monotheism).

(147) And those whom they invoke instead of Him have no power of intercession - except for those who bear witness to the truth knowingly (i.e. believed in the oneness of Allah, and obeyed His Orders), and they know (the facts about the oneness of Allah).

(148) We sent it (this Qur'an) down on a blessed night [(i.e. night of Al-Qadr, Surah No. 97) in the month of Ramadan - the 9th month of the Islamic calendar]. Verily, We are ever warning [mankind that Our Torment will reach those who disbelieve in Our oneness of Lordship and in Our oneness of worship].

(149) Or do those who earn evil deeds think that We shall hold them equal with those who believe (in the oneness of Allah - Islamic Monotheism) and do righteous good deeds, in their present life and after their death? Worst is the judgement that they make.

(150) Then, as for those who believed (in the oneness of Allah - Islamic Monotheism) and did righteous good deeds, their Lord will admit them to His Mercy. That will be the evident success.
