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

(21) Swaying between this (and that), (belonging) neither to these nor to those. He whom Allah causeth to go astray, thou (O Muhammad) wilt not find a way for him:

(22) Lo! those who disbelieve and deal in wrong, Allah will never forgive them, neither will He guide them unto a road,

(23) Lo! those who believe, and those who are Jews, and Sabaeans, and Christians - Whosoever believeth in Allah and the Last Day and doeth right - there shall no fear come upon them neither shall they grieve.

(24) Say: Serve ye in place of Allah that which possesseth for you neither hurt nor use? Allah it is Who is the Hearer, the Knower.

(25) We send not the messengers save as bearers of good news and warners. Whoso believeth and doeth right, there shall no fear come upon them neither shall they grieve.

(26) Say: Shall we cry, instead of unto Allah, unto that which neither profiteth us nor hurteth us, and shall we turn back after Allah hath guided us, like one bewildered whom the devils have infatuated in the earth, who hath companions who invite him to the guidance (saying): Come unto us? Say: Lo! the guidance of Allah is Guidance, and we are ordered to surrender to the Lord of the Worlds,

(27) Say: I find not in that which is revealed unto me aught prohibited to an eater that he eat thereof, except it be carrion, or blood poured forth, or swineflesh - for that verily is foul - or the abomination which was immolated to the name of other than Allah. But whoso is compelled (thereto), neither craving nor transgressing, (for him) lo! thy Lord is Forgiving, Merciful.

(28) They who are idolaters will say: Had Allah willed, we had not ascribed (unto Him) partners neither had our fathers, nor had we forbidden aught. Thus did those who were before them give the lie (to Allah's messengers) till they tasted of the fear of Us. Say: Have ye any knowledge that ye can adduce for Us? Lo! ye follow naught but an opinion, Lo! ye do but guess.

(29) O Children of Adam! When messengers of your own come unto you who narrate unto you My revelations, then whosoever refraineth from evil and amendeth - there shall no fear come upon them neither shall they grieve.

(30) They said: O Moses! either throw (first) or let us be the first throwers?
