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

(251) The leaders of those who were arrogant among his people said to those who were counted weak - to such of them as believed: "Know you that Salih is one sent from his Lord." They said: "We indeed believe in that with which he has been sent."

(252) So they killed the she-camel and insolently defied the Commandment of their Lord, and said: "O Salih! Bring about your threats if you are indeed one of the Messengers (of Allah)."

(253) And (remember) Lut (Lot), when he said to his people: "Do you commit the worst sin such as none preceding you has committed in the 'Alamin (mankind and jinn)?

(254) And We rained down on them a rain (of stones). Then see what was the end of the Mujrimun (criminals, polytheists and sinners).

(255) And to (the people of) Madyan (Midian), (We sent) their brother Shu'aib. He said: "O my people! Worship Allah! You have no other Ilah (God) but Him. [La ilaha illallah (none has the right to be worshipped but Allah)]." Verily, a clear proof (sign) from your Lord has come unto you; so give full measure and full weight and wrong not men in their things, and do not do mischief on the earth after it has been set in order, that will be better for you, if you are believers.

(256) "We should have invented a lie against Allah if we returned to your religion, after Allah has rescued us from it. And it is not for us to return to it unless Allah, our Lord, should will. Our Lord comprehends all things in His Knowledge. In Allah (Alone) we put our trust. Our Lord! Judge between us and our people in truth, for You are the Best of those who give judgment."

(257) Did they then feel secure against the Plan of Allah? None feels secure from the Plan of Allah except the people who are the losers.

(258) [Fir'aun (Pharaoh)] said: "If you have come with a sign, show it forth, if you are one of those who tell the truth."

(259) And We brought the Children of Israel (with safety) across the sea, and they came upon a people devoted to some of their idols (in worship). They said: "O Musa (Moses)! Make for us an ilah (a god) as they have alihah (gods)." He said: "Verily, you are a people who know not (the Majesty and Greatness of Allah and what is obligatory upon you, i.e. to worship none but Allah Alone, the one and the Only God of all that exists)."

(260) And We appointed for Musa (Moses) thirty nights and added (to the period) ten (more), and he completed the term, appointed by his Lord, of forty nights. And Musa (Moses) said to his brother Harun (Aaron): "Replace me among my people, act in the Right Way (by ordering the people to obey Allah and to worship Him Alone) and follow not the way of the Mufsidun (mischief-makers)."
