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

(111) This is the creation of Allah. So show Me that which those (whom you worship) besides Him have created. Nay, the Zalimun (polytheists, wrongdoers and those who do not believe in the oneness of Allah) are in plain error.

(112) "O my son! Aqim-As-Salat (perform As-Salat), enjoin (on people) Al-Ma'ruf - (Islamic Monotheism and all that is good), and forbid (people) from Al-Munkar (i.e. disbelief in the oneness of Allah, polytheism of all kinds and all that is evil and bad), and bear with patience whatever befalls you. Verily, these are some of the important commandments (ordered by Allah with no exemption).

(113) As for those who believe (in the oneness of Allah - Islamic Monotheism) and do righteous good deeds, for them are Gardens (Paradise) as an entertainment for what they used to do.

(114) And announce to the believers (in the oneness of Allah and in His Messenger Muhammad صلى الله عليه وسلم) the glad tidings, that they will have from Allah a Great Bounty.

(115) So that Allah will punish the hypocrites, men and women, and the men and women who are Al-Mushrikun (polytheists, idolaters, pagans, disbelievers, in the oneness of Allah, and His Messenger Muhammad صلى الله عليه وسلم). And Allah will pardon (accept the repentance of) the true believers of the Islamic Monotheism, men and women. And Allah is Ever Oft-Forgiving, Most Merciful.

(116) That He may recompense those who believe (in the oneness of Allah - Islamic Monotheism) and do righteous good deeds. Those, theirs is forgiveness and Rizq Karim (generous provision, i.e. Paradise).

(117) See they not what is before them and what is behind them, of the heaven and the earth? If We will, We shall sink the earth with them, or cause a piece of the heaven to fall upon them. Verily, in this is a sign for every slave who turns to Allah in repentance (i.e. the one who believes in the oneness of Allah and performs deeds of His obedience and always begs His Pardon).

(118) And indeed Iblis (Satan) did prove true his thought about them: and they followed him, all except a group of true believers (in the oneness of Allah).

(119) Indeed they did disbelieve (in the oneness of Allah, Islam, the Qur'an and Muhammad صلى الله عليه وسلم) before (in this world), and they (used to) conjecture about the Unseen [i.e. the Hereafter, Hell, Paradise, Resurrection and the Promise of Allah (by saying) all that is untrue], from a far place.

(120) Those who disbelieve, theirs will be a severe torment; and those who believe (in the oneness of Allah - Islamic Monotheism) and do righteous good deeds, theirs will be forgiveness and a great reward (i.e. Paradise).
