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

(371) That they may witness advantages for them and mention the name of Allah during stated days over what He has given them of the cattle quadrupeds, then eat of them and feed the distressed one, the needy.

(372) And to every nation We appointed acts of devotion that they may mention the name of Allah on what He has given them of the cattle quadrupeds; so your god is one God, therefore to Him should you submit, and give good news to the humble,

(373) (To) those whose hearts tremble when Allah is mentioned, and those who are patient under that which afflicts them, and those who keep up prayer, and spend (benevolently) out of what We have given them.

(374) Surely Allah will defend those who believe; surely Allah does not love any one who is unfaithful, ungrateful.

(375) Then We made the seed a clot, then We made the clot a lump of flesh, then We made (in) the lump of flesh bones, then We clothed the bones with flesh, then We caused it to grow into another creation, so blessed be Allah, the best of the creators.

(376) So We revealed to him, saying: Make the ark before Our eyes and (according to) Our revelation; and when Our command is given and the valley overflows, take into it of every kind a pair, two, and your followers, except those among them against whom the word has gone forth, and do not speak to Me in respect of those who are unjust; surely they shall be drowned.

(377) What! does he threaten you that when you are dead and become dust and bones that you shall then be brought forth?

(378) No people can hasten on their doom nor can they postpone (it).

(379) Then We sent Our apostles one after another; whenever there came to a people their apostle, they called him a liar, so We made some of them follow others and We made them stories; so away with a people who do not believe!

(380) And surely this your religion is one religion and I am your Lord, therefore be careful (of your duty) to Me.
