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

(191) And He is Allah (to be worshipped Alone) in the heavens and on the earth; He knows what you conceal and what you reveal, and He knows what you earn (good or bad). (See V.43:84)

(192) Say (O Muhammad صلى الله عليه وسلم): "To whom belongs all that is in the heavens and the earth?" Say: "To Allah. He has prescribed Mercy for Himself. Indeed He will gather you together on the Day of Resurrection, about which there is no doubt. Those who have lost themselves will not believe [in Allah as being the only Ilah (God), and Muhammad صلى الله عليه وسلم as being one of His Messengers, and in Resurrection].

(193) Say (O Muhammad صلى الله عليه وسلم): "Shall I take as a Wali (Helper, Protector, Lord or God) any other than Allah, the Creator of the heavens and the earth? And it is He Who feeds but is not fed." Say: "Verily, I am commanded to be the first of those who submit themselves to Allah (as Muslims)." And be not you (O Muhammad صلى الله عليه وسلم) of the Mushrikun [polytheists, pagans, idolaters and disbelievers in the oneness of Allah]. (Tafsir Al-Qurtubi)

(194) And if Allah touches you with harm, none can remove it but He, and if He touches you with good, then He is Able to do all things.

(195) Say (O Muhammad صلى الله عليه وسلم): "What thing is the most great in witness?" Say: "Allah (the Most Great!) is Witness between me and you; this Qur'an has been revealed to me that I may therewith warn you and whomsoever it may reach. Can you verily bear witness that besides Allah there are other alihah (gods)?" Say "I bear no (such) witness!" Say: "But in truth He (Allah) is the only one Ilah (God). And truly I am innocent of what you join in worship with Him."

(196) And of them there are some who listen to you; but We have set veils on their hearts, so they understand it not, and deafness in their ears; and even if they see every one of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) they will not believe therein; to the point that when they come to you to argue with you, the disbelievers say: "These are nothing but tales of the men of old."

(197) Verily, (many) Messengers were denied before you (O Muhammad صلى الله عليه وسلم), but with patience they bore the denial, and they were hurt; till Our Help reached them, and none can alter the Words (Decisions) of Allah. Surely there has reached you the information (news) about the Messengers (before you).

(198) If their aversion (from you, O Muhammad صلى الله عليه وسلم and from that with which you have been sent) is hard on you, (and you cannot be patient of their harm to you), then if you were able to seek a tunnel in the earth or a ladder to the sky, so that you may bring them a sign (and you cannot do it, so be patient). And had Allah willed, He could have gathered them together (all) on true guidance, so be not you one of those who are Al-Jahilun (the ignorant).

(199) Say (O Muhammad صلى الله عليه وسلم): "Tell me if Allah's Torment comes upon you, or the Hour comes upon you, would you then call upon any one other than Allah? (Reply) if you are truthful!"

(200) Nay! To Him Alone you would call, and, if He wills, He would remove that (distress) for which you call upon Him, and you would forget at that time whatever partners you joined (with Him in worship)!
