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

(771) 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).

(772) 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).

(773) And to Solomon (We subjected) the wind, its morning (stride from sunrise till midnoon) was a month's (journey), and its afternoon (stride from the midday decline of the sun to sunset) was a month's (journey i.e. in one day he could travel two months' (journey). And We caused a fount of (molten) brass to flow for him, and there were jinn that worked in front of him, by the Leave of his Lord. And whosoever of them turned aside from Our Command, We shall cause him to taste of the torment of the blazing Fire.

(774) 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).

(775) Say (O Muhammad صلى الله عليه وسلم to polytheists and pagans): "Show me those whom you have joined with Him as partners. Nay (there are not at all any partners with Him)! But He is Allah (Alone), the All-Mighty, the All-Wise."

(776) And those who disbelieve say: "We believe not in this Qur'an nor in that which was before it." But if you could see when the Zalimun (polytheists and wrong-doers) will be made to stand before their Lord, how they will cast the (blaming) word one to another! Those who were deemed weak will say to those who were arrogant: "Had it not been for you, we should certainly have been believers!"

(777) So Today (i.e. the Day of Resurrection), none of you can profit or harm one another. And We shall say to those who did wrong [i.e. worshipped others (like the angels, jinn, prophets, saints, righteous persons) along with Allah]: "Taste the torment of the Fire which you used to belie.

(778) Say (to them O Muhammad صلى الله عليه وسلم): "I exhort you to one (thing) only: that you stand up for Allah's sake in pairs and singly, and reflect (within yourselves the life history of the Prophet صلى الله عليه وسلم): there is no madness in your companion (Muhammad صلى الله عليه وسلم). He is only a warner to you in face of a severe torment."

(779) 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.

(780) And a barrier will be set between them and that which they desire [i.e. At-Taubah (turning to Allah in repentance) and the accepting of Faith], as was done in the past with the people of their kind. Verily, they have been in grave doubt.
