The word(s) "one" appears 748 time(s) in 667 verse(s) in Quran in Muhammad Pickthal translation.

(621) And indeed they supposed, even as ye suppose, that Allah would not raise anyone (from the dead) -

(622) And the places of worship are only for Allah, so pray not unto anyone along with Allah.

(623) Say: Lo! none can protect me from Allah, nor can I find any refuge beside Him

(624) (He is) the Knower of the Unseen, and He revealeth unto none His secret,

(625) Lord of the East and the West; there is no Allah save Him; so choose thou Him alone for thy defender -

(626) Leave Me (to deal) with him whom I created lonely,

(627) We have appointed only angels to be wardens of the Fire, and their number have We made to be a stumbling-block for those who disbelieve; that those to whom the Scripture hath been given may have certainty, and that believers may increase in faith; and that those to whom the Scripture hath been given and believers may not doubt; and that those in whose hearts there is disease, and disbelievers, may say: What meaneth Allah by this similitude? Thus Allah sendeth astray whom He will, and whom He will He guideth. None knoweth the hosts of thy Lord save Him. This is naught else than a Reminder unto mortals.

(628) Lo! this is one of the greatest (portents)

(629) In gardens they will ask one another

(630) Nay, but everyone of them desireth that he should be given open pages (from Allah).
