The word(s) "one" appears 806 time(s) in 722 verse(s) in Quran in Muhammad Habib Shakir translation.

(671) And that they thought as you think, that Allah would not raise anyone:

(672) And that the mosques are Allah's, therefore call not upon any one with Allah:

(673) Say: I only call upon my Lord, and I do not associate any one with Him.

(674) Say: Surely no one can protect me against Allah, nor can I find besides Him any place of refuge:

(675) Leave Me and him whom I created alone,

(676) And We have not made the wardens of the fire others than angels, and We have not made their number but as a trial for those who disbelieve, that those who have been given the book may be certain and those who believe may increase in faith, and those who have been given the book and the believers may not doubt, and that those in whose hearts is a disease and the unbelievers may say: What does Allah mean by this parable? Thus does Allah make err whom He pleases, and He guides whom He pleases, and none knows the hosts of your Lord but He Himself; and this is naught but a reminder to the mortals.

(677) Surely it (hell) is one of the gravest (misfortunes),

(678) Nay; every one of them desires that he may be given pages spread out;

(679) Does man think that We shall not gather his bones?

(680) With your Lord alone shall on that day be the place of rest.
