The word(s) "one" appears 1507 time(s) in 1150 verse(s) in Quran in Mohsin Khan translation.

(31) And (remember) when We made the House (the Ka'bah at Makkah) a place of resort for mankind and a place of safety. And take you (people) the Maqam (place) of Ibrahim (Abraham) [or the stone on which Ibrahim (Abraham) عليه السلام stood while he was building the Ka'bah] as a place of prayer (for some of your prayers, e.g. two Rak'at after the Tawaf of the Ka'bahat Makkah), and We commanded Ibrahim (Abraham) and Isma'il (Ishmael) that they should purify My House (the Ka'bah at Makkah) for those who are circumambulating it, or staying (I'tikaf), or bowing or prostrating themselves (there, in prayer).

(32) Our Lord! And make us submissive unto You and of our offspring a nation submissive unto You, and show us our Manasik (all the ceremonies of pilgrimage - Hajjand 'Umrah), and accept our repentance. Truly, You are the one Who accepts repentance, the Most Merciful.

(33) Or were you witnesses when death approached Ya'qub (Jacob)? When he said unto his sons, "What will you worship after me?" They said, "We shall worship your Ilah (God - Allah), the Ilah (God) of your fathers, Ibrahim (Abraham), Isma'il (Ishmael), Ishaq (Isaac), one Ilah (God), and to Him we submit (in Islam)."

(34) And they say, "Be Jews or Christians, then you will be guided." Say (to them O Muhammad صلى الله عليه وسلم), "Nay, (we follow) only the religion of Ibrahim (Abraham), Hanifa [Islamic Monotheism, i.e. to worship none but Allah (Alone)], and he was not of Al-Mushrikun (those who worshipped others along with Allah - see V.2:105)."

(35) Say (O Muhammad صلى الله عليه وسلم to the Jews and Christians), "Dispute you with us about Allah while He is our Lord and your Lord? And we are to be rewarded for our deeds and you for your deeds. And we are sincere to Him [in worship and obedience (i.e. we worship Him Alone and none else, and we obey His Orders)]."

(36) And even if you were to bring to the people of the Scripture (Jews and Christians) all the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they would not follow your Qiblah (prayer direction), nor are you going to follow their Qiblah (prayer direction). And they will not follow each other's Qiblah (prayer direction). Verily, if you follow their desires after that which you have received of knowledge (from Allah), then indeed you will be one of the Zalimun (polytheists, wrong-doers).

(37) (This is) the truth from your Lord. So be you not one of those who doubt.

(38) They are those on whom are the Salawat (i.e. who are blessed and will be forgiven) from their Lord, and (they are those who) receive His Mercy, and it is they who are the guided ones.

(39) Verily, those who conceal the clear proofs, evidence and the guidance, which We have sent down, after We have made it clear for the people in the Book, they are the ones cursed by Allah and cursed by the cursers.

(40) Except those who repent and do righteous deeds, and openly declare (the truth which they concealed). These, I will accept their repentance. And I am the one Who accepts repentance, the Most Merciful.
