The word(s) "one" appears 1507 time(s) in 1150 verse(s) in Quran in Mohsin Khan translation.

(881) "You invite me to disbelieve in Allah (and in His oneness), and to join partners in worship with Him of which I have no knowledge; and I invite you to the All-Mighty, the Oft-Forgiving!

(882) "No doubt you call me to (worship) one who cannot grant (me) my request (or respond to my invocation) in this world or in the Hereafter. And our return will be to Allah, and Al-Musrifun (i.e. polytheists and arrogants, those who commit great sins, the transgressors of Allah's set limits): they shall be the dwellers of the Fire!

(883) Verily, We will indeed make victorious Our Messengers and those who believe (in the oneness of Allah - Islamic Monotheism) in this world's life and on the Day when the witnesses will stand forth, (i.e. Day of Resurrection) -

(884) The Day when their excuses will be of no profit to Zalimun (polytheists, wrong-doers and disbelievers in the oneness of Allah). Theirs will be the curse, and theirs will be the evil abode (i.e. painful torment in Hell-fire).

(885) And not equal are the blind and those who see; nor are (equal) those who believe (in the oneness of Allah - Islamic Monotheism), and do righteous good deeds, and those who do evil. Little do you remember!

(886) And your Lord said: "Invoke Me, [i.e. believe in My oneness (Islamic Monotheism) and ask Me for anything] I will respond to your (invocation). Verily! Those who scorn My worship [i.e. do not invoke Me, and do not believe in My oneness, (Islamic Monotheism)] they will surely enter Hell in humiliation!"

(887) That is Allah, your Lord, the Creator of all things: La ilaha illa Huwa (none has the right to be worshipped but He). How then are you turning away (from Allah, by worshipping others instead of Him)?

(888) He is the Ever Living, La ilaha illa Huwa (none has the right to be worshipped but He); so invoke Him making your worship pure for Him Alone (by worshipping Him Alone, and none else, and by doing righteous deeds sincerely for Allah's sake only, and not to show off, and not setting up rivals with Him in worship). All the praises and thanks be to Allah, the Lord of the 'Alamin (mankind, jinn and all that exists).

(889) Those who deny the Book (this Qur'an), and that with which We sent Our Messengers (i.e. to worship none but Allah Alone sincerely, and to reject all false deities and to confess resurrection after the death for recompense) they will come to know (when they will be cast into the Fire of Hell).

(890) And He shows you His Ayat (signs and proofs) (of His oneness in all the above-mentioned things). Which, then of the Ayat (signs and proofs) of Allah do you deny?
