The word(s) "one" appears 1001 time(s) in 857 verse(s) in Quran in Abdullah Yusuf Ali translation.

(321) Your Allah is one Allah: as to those who believe not in the Hereafter, their hearts refuse to know, and they are arrogant.

(322) If thou art anxious for their guidance, yet Allah guideth not such as He leaves to stray, and there is none to help them.

(323) And to Allah doth obeisance all that is in the heavens and on earth, whether moving (living) creatures or the angels: for none are arrogant (before their Lord).

(324) Allah has said: "Take not (for worship) two gods: for He is just one Allah: then fear Me (and Me alone)."

(325) When news is brought to one of them, of (the birth of) a female (child), his face darkens, and he is filled with inward grief!

(326) Allah sets forth the Parable (of two men: one) a slave under the dominion of another; He has no power of any sort; and (the other) a man on whom We have bestowed goodly favours from Ourselves, and he spends thereof (freely), privately and publicly: are the two equal? (By no means;) praise be to Allah. But most of them understand not.

(327) Allah sets forth (another) Parable of two men: one of them dumb, with no power of any sort; a wearisome burden is he to his master; whichever way be directs him, he brings no good: is such a man equal with one who commands Justice, and is on a Straight Way?

(328) one Day We shall raise from all Peoples a Witness: then will no excuse be accepted from Unbelievers, nor will they receive any favours.

(329) one day We shall raise from all Peoples a witness against them, from amongst themselves: and We shall bring thee as a witness against these (thy people): and We have sent down to thee the Book explaining all things, a Guide, a Mercy, and Glad Tidings to Muslims.

(330) And be not like a woman who breaks into untwisted strands the yarn which she has spun, after it has become strong. Nor take your oaths to practise deception between yourselves, lest one party should be more numerous than another: for Allah will test you by this; and on the Day of Judgment He will certainly make clear to you (the truth of) that wherein ye disagree.
