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

(121) But those who disbelieve (in the oneness of Allah - Islamic Monotheism), for them will be the Fire of Hell. Neither will it have a complete killing effect on them so that they die, nor shall its torment be lightened for them. Thus do We requite every disbeliever!

(122) Shall We treat those who believe (in the oneness of Allah - Islamic Monotheism) and do righteous good deeds as Mufsidun (those who associate partners in worship with Allah and commit crimes) on earth? Or shall We treat the Muttaqun (the pious - See V.2:2) as the Fujjar (criminals, disbelievers, the wicked)?

(123) This is so! And for the Taghun (transgressors, the disobedient to Allah and His Messenger - disbelievers in the oneness of Allah, criminals) will be an evil final return (Fire).

(124) Say (O Muhammad صلى الله عليه وسلم): "O My slaves who believe (in the oneness of Allah - Islamic Monotheism), be afraid of your Lord (Allah) and keep your duty to Him. Good is (the reward) for those who do good in this world, and Allah's earth is spacious (so if you cannot worship Allah at a place, then go to another)! Only those who are patient shall receive their reward in full, without reckoning. "

(125) And when Allah Alone is mentioned, the hearts of those who believe not in the Hereafter are filled with disgust (from the oneness of Allah توحيد الله) and when those (whom they obey or worship) besides Him [like all false deities other than Allah, - it may be a Messenger, an angel, a pious man, a jinni, or any other creature even idols, graves of religious people, saints, priests, monks and others.] are mentioned, behold, they rejoice!

(126) And those who did wrong (the polytheists and disbelievers in the oneness of Allah), if they had all that is in earth and therewith as much again, they verily, would offer it to ransom themselves therewith on the Day of Resurrection from the evil torment; and there will become apparent to them from Allah what they had not been reckoning.

(127) Those (angels) who bear the Throne (of Allah) and those around it glorify the praises of their Lord, and believe in Him, and ask forgiveness for those who believe (in the oneness of Allah) (saying): "Our Lord! You comprehend all things in mercy and knowledge, so forgive those who repent and follow Your Way, and save them from the torment of the blazing Fire!

(128) So, call you (O Muhammad صلى الله عليه وسلم and the believers) upon (or invoke) Allah making (your) worship pure for Him (Alone) (by worshipping none but Him and by doing religious deeds sincerely for Allah's sake only and not to show off and not to set up rivals with Him in worship), however much the disbelievers (in the oneness of Allah) may hate (it).

(129) And indeed Yusuf (Joseph) did come to you, in times gone by, with clear signs, but you ceased not to doubt in that which he did bring to you: till when he died you said: "No Messenger will Allah send after him." Thus Allah leaves astray him who is a Musrif (a polytheist, an oppressor, a criminal, sinner who commit great sins) and a Murtab (one who doubts Allah's Warning and His oneness).

(130) "Whosoever does an evil deed, will not be requited except the like thereof; and whosoever does a righteous deed, whether male or female and is a true believer (in the oneness of Allah), such will enter Paradise, where they will be provided therein (with all things in abundance) without limit.
