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

(921) And similarly, We sent not a warner before you (O Muhammad صلى الله عليه و سلم) to any town (people) but the luxurious ones among them said: "We found our fathers following a certain way and religion, and we will indeed follow their footsteps."

(922) "Except Him (i.e. I worship none but Allah Alone) Who did create me; and verily He will guide me."

(923) And he made it [i.e. La ilaha illallah (none has the right to be worshipped but Allah Alone)] a Word lasting among his offspring, (True Monotheism), that they may turn back (i.e. to repent to Allah or receive admonition).

(924) And were it not that mankind would have become of one community (all disbelievers, desiring worldly life only), We would have provided for those who disbelieve in the Most Gracious (Allah), silver roofs for their houses, and elevators whereby they ascend,

(925) And for their houses, doors (of silver), and thrones (of silver) on which they could recline,

(926) And adornments of gold. Yet all this (i.e. the roofs, doors, stairs, elevators, thrones of their houses) would have been nothing but an enjoyment of this world. And the Hereafter with your Lord is (only) for the Muttaqun.

(927) Till, when (such a one) comes to Us, he says [to his Qarin (Satan / devil companion)] "Would that between me and you were the distance of the two easts (or the east and west)" - a worst (type of) companion (indeed)!

(928) And verily this (the Qur'an) is indeed a Reminder for you (O Muhammad صلى الله عليه و سلم) and your people (Quraish people, or your followers), and you will be questioned (about it).

(929) "Am I not better than this one [Musa (Moses)] who is despicable and can scarcely express himself clearly?

(930) "Verily, Allah! He is my Lord (God) and your Lord (God). So worship Him (Alone). This is the (only) Straight Path (i.e. Allah's religion of true Islamic Monotheism)."
