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

(31) Those who follow the messenger, the Prophet who can neither read nor write, whom they will find described in the Torah and the Gospel (which are) with them. He will enjoin on them that which is right and forbid them that which is wrong. He will make lawful for them all good things and prohibit for them only the foul; and he will relieve them of their burden and the fetters that they used to wear. Then those who believe in him, and honour him, and help him, and follow the light which is sent down with him: they are the successful.

(32) Say (O Muhammad): O mankind! Lo! I am the messenger of Allah to you all - (the messenger of) Him unto Whom belongeth the Sovereignty of the heavens and the earth. There is no Allah save Him. He quickeneth and He giveth death. So believe in Allah and His messenger, the Prophet who can neither read nor write, who believeth in Allah and in His Words, and follow him that haply ye may be led aright.

(33) When ye were on the near bank (of the valley) and they were on the yonder bank, and the caravan was below you (on the coast plain). And had ye trysted to meet one another ye surely would have failed to keep the tryst, but (it happened, as it did, without the forethought of either of you) that Allah might conclude a thing that must be done; that he who perished (on that day) might perish by a clear proof (of His Sovereignty) and he who survived might survive by a clear proof (of His Sovereignty). Lo! Allah in truth is Hearer, Knower.

(34) And they observe toward a believer neither pact nor honour. These are they who are transgressors.

(35) It is not for the townsfolk of Al-Madinah and for those around them of the wandering Arabs so stay behind the messenger of Allah and prefer their lives to his life. That is because neither thirst nor toil nor hunger afflicteth them in the way of Allah, nor step they any step that angereth the disbelievers, nor gain they from the enemy a gain, but a good deed is recorded for them therefor. Lo! Allah loseth not the wages of the good.

(36) See they not that they are tested once or twice in every year? Still they turn not in repentance, neither pay they heed.

(37) They worship beside Allah that which neither hurteth them nor profiteth them, and they say: These are our intercessors with Allah. Say: Would ye inform Allah of (something) that He knoweth not in the heavens or in the earth? Praised be He and High Exalted above all that ye associate (with Him)!

(38) For those who do good is the best (reward) and more (thereto). Neither dust nor ignominy cometh near their faces. Such are rightful owners of the Garden; they will abide therein.

(39) Say (O Muhammad): Who is Lord of the heavens and the earth? Say: Allah. Say: Take ye then (others) beside Him for protectors, which, even for themselves, have neither benefit nor hurt? Say: Is the blind man equal to the seer, or is darkness equal to light? Or assign they unto 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 Almighty.

(40) Tell My bondmen who believe to establish worship and spend of that which We have given them, secretly and publicly, before a day cometh wherein there will be neither traffick nor befriending.
