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

(11) Allah! There is no deity save Him, the Alive, the Eternal. Neither slumber nor sleep overtaketh Him. Unto Him belongeth whatsoever is in the heavens and whatsoever is in the earth. Who is he that intercedeth with Him save by His leave? He knoweth that which is in front of them and that which is behind them, while they encompass nothing of His knowledge save what He will. His throne includeth the heavens and the earth, and He is never weary of preserving them. He is the Sublime, the Tremendous.

(12) Those who spend their wealth for the cause of Allah and afterward make not reproach and injury to follow that which they have spent; their reward is with their Lord, and there shall no fear come upon them, neither shall they grieve.

(13) Those who spend their wealth by night and day, by stealth and openly, verily their reward is with their Lord, and their shall no fear come upon them neither shall they grieve.

(14) Lo! those who believe and do good works and establish worship and pay the poor-due, their reward is with their Lord and there shall no fear come upon them neither shall they grieve.

(15) (On that Day) neither the riches nor the progeny of those who disbelieve will aught avail them with Allah. They will be fuel for Fire.

(16) Lo! those who purchase a small gain at the cost of Allah's covenant and their oaths, they have no portion in the Hereafter. Allah will neither speak to them nor look upon them on the Day of Resurrection, nor will He make them grow. Theirs will be a painful doom.

(17) They will abide therein. Their doom will not be lightened, neither will they be reprieved;

(18) When ye climbed (the hill) and paid no heed to anyone, while the messenger, in your rear, was calling you (to fight). Therefor He rewarded you grief for (his) grief, that (He might teach) you not to sorrow either for that which ye missed or for that which befell you. Allah is Informed of what ye do.

(19) Jubilant (are they) because of that which Allah hath bestowed upon them of His bounty, rejoicing for the sake of those who have not joined them but are left behind: That there shall no fear come upon them neither shall they grieve.

(20) And unto you belongeth a half of that which your wives leave, if they have no child; but if they have a child then unto you the fourth of that which they leave, after any legacy they may have bequeathed, or debt (they may have contracted, hath been paid). And unto them belongeth the fourth of that which ye leave if ye have no child, but if ye have a child then the eighth of that which ye leave, after any legacy ye may have bequeathed, or debt (ye may have contracted, hath been paid). And if a man or a woman have a distant heir (having left neither parent nor child), and he (or she) have a brother or a sister (only on the mother's side) then to each of them twain (the brother and the sister) the sixth, and if they be more than two, then they shall be sharers in the third, after any legacy that may have been bequeathed or debt (contracted) not injuring (the heirs by willing away more than a third of the heritage) hath been paid. A commandment from Allah. Allah is Knower, Indulgent.
