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

(11) And believe in what I have sent down (this Qur'an), confirming that which is with you, [the Taurat (Torah) and the Injeel (Gospel)], and be not the first to disbelieve therein, and buy [get (تاخذ اجرا)] not with My Verses [the Taurat (Torah) and the Injeel (Gospel)] a small price (i.e. getting a small gain by selling My Verses), and fear Me and Me Alone. (Tafsir At-Tabari ).

(12) And (remember) when Musa (Moses) said to his people: "O my people! Verily, you have wronged yourselves by worshipping the calf. So turn in repentance to your Creator and kill yourselves (the innocent kill the wrongdoers among you), that will be better for you with your Creator." Then He accepted your repentance. Truly, He is the one Who accepts repentance, the Most Merciful.

(13) And (remember) when Musa (Moses) asked for water for his people, We said: "Strike the stone with your stick." Then gushed forth therefrom twelve springs. Each (group of) people knew its own place for water. "Eat and drink of that which Allah has provided and do not act corruptly, making mischief on the earth."

(14) And (remember) when you said, "O Musa (Moses)! We cannot endure one kind of food. So invoke your Lord for us to bring forth for us of what the earth grows, its herbs, its cucumbers, its Fum (wheat or garlic), its lentils and its onions." He said, "Would you exchange that which is better for that which is lower? Go you down to any town and you shall find what you want!" And they were covered with humiliation and misery, and they drew on themselves the Wrath of Allah. That was because they used to disbelieve the Ayat (proofs, evidence, verses, lessons, signs, revelations etc.) of Allah and killed the Prophets wrongfully. That was because they disobeyed and used to transgress the bounds (in their disobedience to Allah, i.e. commit crimes and sins).

(15) Then, after that, your hearts were hardened and became as stones or even worse in hardness. And indeed, there are stones out of which rivers gush forth, and indeed, there are of them (stones) which split asunder so that water flows from them, and indeed, there are of them (stones) which fall down for fear of Allah. And Allah is not unaware of what you do.

(16) And when they (Jews) meet those who believe (Muslims), they say, "We believe", but when they meet one another in private, they say, "Shall you (Jews) tell them (Muslims) what Allah has revealed to you [Jews, about the description and the qualities of Prophet Muhammad صلى الله عليه وسلم, that which are written in the Taurat (Torah)] , that they (Muslims) may argue with you (Jews) about it before your Lord?" Have you (Jews) then no understanding?

(17) And those who believe (in the oneness of Allah تعالى - Islamic Monotheism) and do righteous good deeds, they are dwellers of Paradise, they will dwell therein forever. (See V. 2:257)

(18) And (remember) when We took a covenant from the Children of Israel, (saying): Worship none but Allah (Alone) and be dutiful and good to parents, and to kindred, and to orphans and Al-Masakin (the poor), and speak good to people [i.e. enjoin righteousness and forbid evil, and say the truth about Muhammad صلى الله عليه وسلم], and perform As-Salat (Iqamat-as-Salat), and give Zakat. Then you slid back, except a few of you, while you are backsliders. (Tafsir Al-Qurtubi).

(19) After this, it is you who kill one another and drive out a party of you from their homes, assist (their enemies) against them, in sin and transgression. And if they come to you as captives, you ransom them, although their expulsion was forbidden to you. Then do you believe in a part of the Scripture and reject the rest? Then what is the recompense of those who do so among you, except disgrace in the life of this world, and on the Day of Resurrection they shall be consigned to the most grievous torment. And Allah is not unaware of what you do.

(20) But they will never long for it because of what their hands have sent before them (i.e. what they have done). And Allah is All-Aware of the Zalimun (polytheists and wrong-doers).
