The word(s) "either" appears 70 time(s) in 68 verse(s) in Quran in Abdullah Yusuf Ali translation.

(21) How (can there be such a league), seeing that if they get an advantage over you, they respect not in you the ties either of kinship or of covenant? With (fair words from) their mouths they entice you, but their hearts are averse from you; and most of them are rebellious and wicked.

(22) In a Believer they respect not the ties either of kinship or of covenant! It is they who have transgressed all bounds.

(23) Say: "Can you expect for us (any fate) other than one of two glorious things- (Martyrdom or victory)? But we can expect for you either that Allah will send his punishment from Himself, or by our hands. So wait (expectant); we too will wait with you."

(24) Say: "Behold all that is in the heavens and on earth"; but neither Signs nor Warners profit those who believe not.

(25) "'Nor call on any, other than Allah;- Such will neither profit thee nor hurt thee: if thou dost, behold! thou shalt certainly be of those who do wrong.'"

(26) Such are some of the stories of the unseen, which We have revealed unto thee: before this, neither thou nor thy people knew them. So persevere patiently: for the End is for those who are righteous.

(27) He said: "Before any food comes (in due course) to feed either of you, I will surely reveal to you the truth and meaning of this ere it befall you: that is part of the (duty) which my Lord hath taught me. I have (I assure you) abandoned the ways of a people that believe not in Allah and that (even) deny the Hereafter.

(28) Say: "Who is the Lord and Sustainer of the heavens and the earth?" Say: "(It is) Allah." Say: "Do ye then take (for worship) protectors other than Him, such as have no power either for good or for harm to themselves?" Say: "Are the blind equal with those who see? Or the depths of darkness equal with light?" Or do they assign to Allah partners who have created (anything) as He has created, so that the creation seemed to them similar? Say: "Allah is the Creator of all things: He is the One, the Supreme and Irresistible."

(29) Thus have We revealed it to be a judgment of authority in Arabic. Wert thou to follow their (vain) desires after the knowledge which hath reached thee, then wouldst thou find neither protector nor defender against Allah.

(30) Speak to my servants who have believed, that they may establish regular prayers, and spend (in charity) out of the sustenance we have given them, secretly and openly, before the coming of a Day in which there will be neither mutual bargaining nor befriending.
