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

(91) Wherein they will abide for ever, and they will find neither a Wali (a protector) nor a helper.

(92) Say: (O Muhammad صلى الله عليه وسلم to polytheists, pagans) "Call upon those whom you assert (to be associate gods) besides Allah, they possess not even an atom's (or a small ant's) weight either in the heavens or on the earth, nor have they any share in either, nor there is for Him any supporter from among them.

(93) Say (O Muhammad صلى الله عليه وسلم to polytheists, pagans) "Who gives you provision from the heavens and the earth?" Say: "Allah. And verily, (either) we or you are rightly guided or in plain error."

(94) Say (O Muhammad صلى الله عليه وسلم): "Al-Haqq (the truth i.e. the Qur'an and Allah's Revelation) has come, and Al-Batil [falsehood - Iblis (Satan)] can neither create anything nor resurrect (anything)."

(95) But those who disbelieve (in the Oneness of Allah - Islamic Monotheism), for them will be the Fire of Hell. Neither will it have a complete killing effect on them so that they die, nor shall its torment be lightened for them. Thus do We requite every disbeliever!

(96) Neither will they have Ghoul (any kind of hurt, abdominal pain, headache, a sin) from that, nor will they suffer intoxication therefrom.

(97) And warn them (O Muhammad صلى الله عليه وسلم) of the Day that is drawing near (i.e. the Day of Resurrection), when the hearts will be choking the throats, and they can neither return them (hearts) to their chests nor can they throw them out. There will be no friend, nor an intercessor for the Zalimun (polytheists and wrong-doers), who could be given heed to.

(98) And if We had sent this as a Qur'an in a foreign language (other than Arabic), they would have said: "Why are not its verses explained in detail (in our language)? What! (A Book) not in Arabic and (the Messenger) an Arab?" Say: "It is for those who believe, a guide and a healing. And as for those who disbelieve, there is heaviness (deafness) in their ears, and it (the Qur'an) is blindness for them. They are those who are called from a place far away (so they neither listen nor understand)."

(99) And if Allah had willed, He could have made them one nation, but He admits whom He wills to His Mercy. And the Zalimun (polytheists and wrong-doers) will have neither a Wali (protector or guardian) nor a helper.

(100) And you cannot escape from Allah (i.e. His punishment) in the earth, and besides Allah you have neither any Wali (guardian or a protector, helper) nor any helper.
