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

(401) Those who believed (in the oneness of Allah - Islamic Monotheism), and work righteousness, Tuba (all kinds of happiness or name of a tree in Paradise) is for them and a beautiful place of (final) return.

(402) Thus have We sent you (O Muhammad صلى الله عليه و سلم) to a community before whom other communities have passed away, in order that you might recite unto them what We have revealed to you, while they disbelieve in the Most Gracious (Allah) Say: "He is my Lord! La ilaha illa Huwa (none has the right to be worshipped but He)! In Him is my trust, and to Him will be my return with repentance."

(403) Those to whom We have given the Book (such as 'Abdullah bin Salam and other Jews who embraced Islam), rejoice at what has been revealed unto you (i.e. the Qur'an), but there are among the Confederates (from the Jews and pagans) those who reject a part thereof. Say (O Muhammad صلى الله عليه و سلم): "I am commanded only to worship Allah (Alone) and not to join partners with Him. To Him (Alone) I call and to Him is my return."

(404) See they not that We gradually reduce the land (of the disbelievers, by giving it to the believers, in war victories) from its outlying borders. And Allah judges, there is none to put back His Judgement and He is Swift at reckoning.

(405) Alif-Lam-Ra. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings]. (This is) a Book which We have revealed unto you (O Muhammad صلى الله عليه و سلم) in order that you might lead mankind out of darkness (of disbelief and polytheism) into light (of belief in the oneness of Allah and Islamic Monotheism) by their Lord's Leave to the Path of the All-Mighty, the Owner of all Praise.

(406) And (remember) when your Lord proclaimed: "If you give thanks (by accepting Faith and worshipping none but Allah), I will give you more (of My Blessings); but if you are thankless (i.e. disbelievers), verily My punishment is indeed severe."

(407) Has not the news reached you, of those before you, the people of Nuh (Noah), and 'Ad, and Thamud? And those after them? None knows them but Allah. To them came their Messengers with clear proofs, but they put their hands in their mouths (biting them from anger) and said: "Verily, we disbelieve in that with which you have been sent, and we are really in grave doubt as to that to which you invite us (i.e. Islamic Monotheism)."

(408) Their Messengers said to them: "We are no more than human beings like you, but Allah bestows His Grace to whom He wills of His slaves. It is not ours to bring you an authority (proof) except by the Permission of Allah. And in Allah (Alone) let the believers put their trust.

(409) "And why should we not put our trust in Allah while He indeed has guided us our ways? And we shall certainly bear with patience all the hurt you may cause us, and in Allah (Alone) let those who trust, put their trust."

(410) And they (the Messengers) sought victory and help [from their Lord (Allah)]; and every obstinate, arrogant dictator (who refuses to believe in the oneness of Allah) was brought to a complete loss and destruction.
