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

(311) But if they turn away, say (O Muhammad صلى الله عليه وسلم): "Allah is sufficient for me. La ilaha illa Huwa (none has the right to be worshipped but He) in Him I put my trust and He is the Lord of the Mighty Throne."

(312) Alif-Lam-Ra. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings]. These are the Verses of the Book (the Qur'an) Al-Hakim

(313) Is it a wonder for mankind that We have sent Our Revelation to a man from among themselves (i.e. Prophet Muhammad صلى الله عليه وسلم) (saying): "Warn mankind (of the coming torment in Hell), and give good news to those who believe (in the oneness of Allah and in His Prophet Muhammad صلى الله عليه وسلم) that they shall have with their Lord the rewards of their good deeds?" (But) the disbelievers say: "This is indeed an evident sorcerer (i.e. Prophet Muhammad صلى الله عليه وسلم and the Qur'an)!

(314) Surely, your Lord is Allah Who created the heavens and the earth in six Days and then rose over (Istawa ) the Throne (really in a manner that suits His Majesty), disposing the affair of all things. No intercessor (can plead with Him) except after His Leave. That is Allah, your Lord; so worship Him (Alone). Then, will you not remember?

(315) To Him is the return of all of you. The Promise of Allah is true. It is He Who begins the creation and then will repeat it, that He may reward with justice those who believed (in the oneness of Allah - Islamic Monotheism) and did deeds of righteousness. But those who disbelieved will have a drink of boiling fluids and painful torment because they used to disbelieve.

(316) Mankind were but one community (i.e. on one religion - Islamic Monotheism), then they differed (later); and had not it been for a Word that went forth before from your Lord, it would have been settled between them regarding what they differed .

(317) And they say: "How is it that not a sign is sent down on him from his Lord?" Say: "The Unseen belongs to Allah Alone, so wait you, verily, I am with you among those who wait (for Allah's Judgement)."

(318) He it is Who enables you to travel through land and sea, till when you are in the ships, and they sail with them with a favourable wind, and they are glad therein, then comes a stormy wind and the waves come to them from all sides, and they think that they are encircled therein. Then they invoke Allah, making their Faith pure for Him Alone, (saying): "If You (Allah) deliver us from this, we shall truly be of the grateful."

(319) For those who have done good is the best (reward, i.e. Paradise) and even more (i.e. having the honour of glancing at the Countenance of Allah جل جلاله). Neither darkness nor dust nor any humiliating disgrace shall cover their faces. They are the dwellers of Paradise, they will abide therein forever.

(320) Thus is the Word of your Lord justified against those who rebel (disobey Allah) that they will not believe (in the oneness of Allah and in Muhammad صلى الله عليه وسلم as the Messenger of Allah).
