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

(61) And the Book (one's Record) will be placed (in the right hand for a believer in the Oneness of Allah, and in the left hand for a disbeliever in the Oneness of Allah), and you will see the Mujrimun (criminals, polytheists, sinners), fearful of that which is (recorded) therein. They will say: "Woe to us! What sort of Book is this that leaves neither a small thing nor a big thing, but has recorded it with numbers!" And they will find all that they did, placed before them, and your Lord treats no one with injustice.

(62) Until, when he reached the setting place of the sun, he found it setting in a spring of black muddy (or hot) water. And he found near it a people. We (Allah) said (by inspiration): "O Dhul-Qarnain! either you punish them, or treat them with kindness."

(63) And dutiful towards his parents, and he was neither arrogant nor disobedient (to Allah or to his parents).

(64) Then, there has succeeded them a posterity who have given up As-Salat (the prayers) [i.e. made their Salat (prayers) to be lost, either by not offering them or by not offering them perfectly or by not offering them in their proper fixed times] and have followed lusts. So they will be thrown in Hell.

(65) Say (O Muhammad صلى الله عليه وسلم) whoever is in error, the Most Gracious (Allah) will extend (the rope) to him, until, when they see that which they were promised, either the torment or the Hour, they will come to know who is worst in position, and who is weaker in forces. [This is the answer to the question in Verse No.19:73]

(66) [Musa (Moses)] said: "The knowledge thereof is with my Lord, in a Record. My Lord neither errs nor He forgets."

(67) "Then verily, we can produce magic the like thereof; so appoint a meeting between us and you, which neither we nor you shall fail to keep, in an open place where both shall have a just and equal chance (and beholders could witness the competition)."

(68) They said: "O Musa (Moses)! either you throw first or we be the first to throw?"

(69) Verily whoever comes to his Lord as a Mujrim (criminal, polytheist, sinner, disbeliever in the Oneness of Allah and His Messengers), then surely, for him is Hell, wherein he will neither die nor live.

(70) And indeed We revealed to Musa (Moses) (saying): "Travel by night with Ibadi (My slaves) and strike a dry path for them in the sea, fearing neither to be overtaken [by Fir'aun (Pharaoh)] nor being afraid (of drowning in the sea)."
