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

(81) The sovereignty on that Day will be that of Allah (the One Who has no partners). He will judge between them. So those who believed (in the oneness of Allah - Islamic Monotheism) and did righteous good deeds will be in Gardens of delight (Paradise).

(82) And they worship besides Allah others for which He has sent down no authority, and of which they have no knowledge; and for the Zalimun (wrong-doers, polytheists and disbelievers in the oneness of Allah) there is no helper.

(83) So As-Saihah (torment - awful cry) overtook them in truth (with justice), and We made them as rubbish of dead plants. So away with the people who are Zalimun (polytheists, wrong-doers, disbelievers in the oneness of Allah, disobedient to His Messengers).

(84) They will say: "Allah." Say: "Will you not then fear Allah (believe in His oneness, obey Him, believe in the Resurrection and Recompense for every good or bad deed)?"

(85) And whoever invokes (or worships), besides Allah, any other ilah (god), of whom he has no proof; then his reckoning is only with his Lord. Surely! Al-Kafirun (the disbelievers in Allah and in the oneness of Allah, polytheists, pagans, idolaters) will not be successful.

(86) The true believers are only those, who believe in (the oneness of) Allah and His Messenger (Muhammad صلى الله عليه وسلم): and when they are with him on some common matter, they go not away until they have asked his permission. Verily those who ask your permission, those are they who (really) believe in Allah and His Messenger. So if they ask your permission for some affairs of theirs, give permission to whom you will of them, and ask Allah for their forgiveness. Truly, Allah is Oft-Forgiving, Most Merciful.

(87) The sovereignty on that Day will be the true (sovereignty), belonging to the Most Gracious (Allah), and it will be a hard Day for the disbelievers (those who disbelieve in the oneness of Allah - Islamic Monotheism).

(88) Except those who believe (in the oneness of Allah - Islamic Monotheism) and do righteous deeds, and remember Allah much, and vindicate themselves after they have been wronged [by replying back in poetry to the unjust poetry (which the pagan poets utter against the Muslims)]. And those who do wrong will come to know by what overturning they will be overturned.

(89) A guide (to the Right Path) and glad tidings for the believers [who believe in the oneness of Allah (i.e. Islamic Monotheism)].

(90) And they (the disbelievers in the oneness of Allah) say: "When (will) this promise (be fulfilled), if you are truthful?"
