The word(s) "either" appears 129 time(s) in 125 verse(s) in Quran in Mohsin Khan translation.

(51) "And I have followed the religion of my fathers, - Ibrahim (Abraham), Ishaq (Isaac) and Ya'qub (Jacob) [عليهم السلام], and never could we attribute any partners whatsoever to Allah. This is from the Grace of Allah to us and to mankind, but most men thank not (i.e. they neither believe in Allah, nor worship Him).

(52) And if you (O Muhammad صلى الله عليه و سلم) wonder (at these polytheists who deny your message of Islamic Monotheism and have taken besides Allah others for worship who can neither harm nor benefit), then wondrous is their saying: "When we are dust, shall we indeed then be (raised) in a new creation?" They are those who disbelieved in their Lord! They are those who will have iron chains tying their hands to their necks. They will be the dwellers of the Fire to abide therein.

(53) Say (O Muhammad صلى الله عليه و سلم): "Who is the Lord of the heavens and the earth?" Say: "(It is) Allah." Say: "Have you then taken (for worship) Auliya' (protectors) other than Him, such as have no power either for benefit or for harm to themselves?" Say: "Is the blind equal to the one who sees? Or darkness equal to light? Or do they assign to Allah partners who created the like of His creation, so that the creation (which they made and His creation) seemed alike to them?" Say: "Allah is the Creator of all things; and He is the One, the Irresistible."

(54) Say (O Muhammad صلى الله عليه و سلم) to 'Ibadi (My slaves) who have believed, that they should perform As-Salat (Iqamat-as-Salat ), and spend in charity out of the sustenance We have given them, secretly and openly, before the coming of a Day on which there will be neither mutual bargaining nor befriending.

(55) And those who joined others in worship with Allah said: "If Allah had so willed, neither we nor our fathers would have worshipped aught but Him, nor would we have forbidden anything without (Command from) Him." So did those before them. Then! Are the Messengers charged with anything but to convey clearly the Message?

(56) And if Allah were to seize mankind for their wrong-doing, He would not leave on it (the earth) a single moving (living) creature, but He postpones them for an appointed term and when their term comes, neither can they delay nor can they advance it an hour (or a moment).

(57) (He was) thankful for His (Allah's) Favours. He (Allah) chose him (as an intimate friend) and guided him to a Straight Path (Islamic Monotheism - neither Judaism nor Christianity ).

(58) And walk not on the earth with conceit and arrogance. Verily, you can neither rend nor penetrate the earth, nor can you attain a stature like the mountains in height.

(59) Say (O Muhammad صلى الله عليه و سلم): "Call upon those - besides Him - whom you pretend [to be gods like angels, 'Îsa (Jesus), 'Uzair (Ezra), and others.]. They have neither the power to remove the adversity from you nor even to shift it from you to another person."

(60) Say (O Muhammad صلى الله عليه و سلم): "Invoke Allah or invoke the Most Gracious (Allah), by whatever name you invoke Him (it is the same), for to Him belong the Best Names. And offer your Salat (prayer) neither aloud nor in a low voice, but follow a way between.
