The word(s) "either" appears 81 time(s) in 80 verse(s) in Quran in Muhammad Pickthal translation.

(51) Nay, but it will come upon them unawares so that it will stupefy them, and they will be unable to repel it, neither will they be reprieved.

(52) Allah is the Light of the heavens and the earth. The similitude of His light is as a niche wherein is a lamp. The lamp is in a glass. The glass is as it were a shining star. (This lamp is) kindled from a blessed tree, an olive neither of the East nor of the West, whose oil would almost glow forth (of itself) though no fire touched it. Light upon light. Allah guideth unto His light whom He will. And Allah speaketh to mankind in allegories, for Allah is Knower of all things.

(53) Men whom neither merchandise nor sale beguileth from remembrance of Allah and constancy in prayer and paying to the poor their due; who fear a day when hearts and eyeballs will be overturned;

(54) Thus they will give you the lie regarding what ye say, then ye can neither avert (the doom) nor obtain help. And whoso among you doeth wrong, We shall make him taste great torment.

(55) Yet they worship instead of Allah that which can neither benefit them nor hurt them. The disbeliever was ever a partisan against his Lord.

(56) And those who, when they spend, are neither prodigal nor grudging; and there is ever a firm station between the two;

(57) Say (unto them): On the day of the victory the faith of those who disbelieve (and who then will believe) will not avail them, neither will they be reprieved.

(58) Say (O Muhammad): Call upon those whom ye set up beside Allah! They possess not an atom's weight either in the heavens or in the earth, nor have they any share in either, nor hath He an auxiliary among them.

(59) And if We will, We drown them, and there is no help for them, neither can they be saved;

(60) And the blind man and the seer are not equal, neither are those who believe and do good works (equal with) the evil-doer. Little do ye reflect!
