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

(371) "Why didst thou not, as thou wentest into thy garden, say: 'Allah's will (be done)! There is no power but with Allah!' If thou dost see me less than thee in wealth and sons,

(372) There, the (only) protection comes from Allah, the True one. He is the Best to reward, and the Best to give success.

(373) one Day We shall remove the mountains, and thou wilt see the earth as a level stretch, and We shall gather them, all together, nor shall We leave out any one of them.

(374) And the Book (of Deeds) will be placed (before you); and thou wilt see the sinful in great terror because of what is (recorded) therein; they will say, "Ah! woe to us! what a Book is this! It leaves out nothing small or great, but takes account thereof!" They will find all that they did, placed before them: And not one will thy Lord treat with injustice.

(375) Behold! We said to the angels, "Bow down to Adam": They bowed down except Iblis. He was one of the Jinns, and he broke the Command of his Lord. Will ye then take him and his progeny as protectors rather than Me? And they are enemies to you! Evil would be the exchange for the wrong-doers!

(376) one Day He will say, "Call on those whom ye thought to be My partners," and they will call on them, but they will not listen to them; and We shall make for them a place of common perdition.

(377) And who doth more wrong than one who is reminded of the Signs of his Lord, but turns away from them, forgetting the (deeds) which his hands have sent forth? Verily We have set veils over their hearts lest they should understand this, and over their ears, deafness, if thou callest them to guidance, even then will they never accept guidance.

(378) He replied: "Sawest thou (what happened) when we betook ourselves to the rock? I did indeed forget (about) the Fish: none but Satan made me forget to tell (you) about it: it took its course through the sea in a marvellous way!"

(379) So they found one of Our servants, on whom We had bestowed Mercy from Ourselves and whom We had taught knowledge from Our own Presence.

(380) So they both proceeded: until, when they were in the boat, he scuttled it. Said Moses: "Hast thou scuttled it in order to drown those in it? Truly a strange thing hast thou done!"
