The word(s) "either" appears 57 time(s) in 57 verse(s) in Quran in Muhammad Habib Shakir translation.

(41) Neither is it allowable to the sun that it should overtake the moon, nor can the night outstrip the day; and all float on in a sphere.

(42) And certainly We had established them in what We have not established you in, and We had given-- them ears and eyes and hearts, but neither their ears, nor their eyes, nor their hearts availed them aught, since they denied the communications of Allah, and that which they mocked encompassed them.

(43) So when you meet in battle those who disbelieve, then smite the necks until when you have overcome them, then make (them) prisoners, and afterwards either set them free as a favor or let them ransom (themselves) until the war terminates. That (shall be so); and if Allah had pleased He would certainly have exacted what is due from them, but that He may try some of you by means of others; and (as for) those who are slain in the way of Allah, He will by no means allow their deeds to perish.

(44) So on that day neither man nor jinni shall be asked about his sin.

(45) In them shall be those who restrained their eyes; before them neither man nor jinni shall have touched them.

(46) Neither intercepted nor forbidden,

(47) Neither cool nor honorable.

(48) Have you not seen those who befriend a people with whom Allah is wroth? They are neither of you nor of them, and they swear falsely while they know.

(49) Neither their wealth nor their children shall avail them aught against Allah; they are the inmates of the fire, therein they shall abide.

(50) O you who believe! when believing women come to you flying, then examine them; Allah knows best their faith; then if you find them to be believing women, do not send them back to the unbelievers, neither are these (women) lawful for them, nor are those (men) lawful for them, and give them what they have spent; and no blame attaches to you in marrying them when you give them their dowries; and hold not to the ties of marriage of unbelieving women, and ask for what you have spent, and let them ask for what they have spent. That is Allah's judgment; He judges between you, and Allah is Knowing, Wise.
