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

(71) Did they not see that it could not return them a word (for answer), and that it had no power either to harm them or to do them good?

(72) He (Allah) said: "Get you down (from the Paradise to the earth), both of you, together, some of you are an enemy to some others. Then if there comes to you guidance from Me, then whoever follows My Guidance he shall neither go astray, nor shall be distressed.

(73) "But whosoever turns away from My Reminder (i.e. neither believes in this Qur'an nor acts on its teachings.) verily, for him is a life of hardship, and We shall raise him up blind on the Day of Resurrection."

(74) [Ibrahim (Abraham)] said: "Do you then worship besides Allah, things that can neither profit you, nor harm you?

(75) He calls besides Allah unto that which can neither harm him, nor profit him. That is a straying far away.

(76) It is neither their meat nor their blood that reaches Allah, but it is piety from you that reaches Him. Thus have We made them subject to you that you may magnify Allah for His Guidance to you. And give glad tidings (O Muhammad صلى الله عليه وسلم) to the Muhsinun (doers of good).

(77) The adulterer-fornicator marries not but an adulteress-fornicatress or a Mushrikah, and the adulteress-fornicatress none marries her except an adulterer-fornicator or a Muskrik [and that means that the man who agrees to marry (have a sexual relation with) a Mushrikah (female polytheist, pagan or idolatress) or a prostitute, then surely he is either an adulterer-fornicator, or a Mushrik (polytheist, pagan or idolater). And the woman who agrees to marry (have a sexual relation with) a Mushrik (polytheist, pagan or idolater) or an adulterer-fornicator, then she is either a prostitute or a Mushrikah (female polytheist, pagan, or idolatress)]. Such a thing is forbidden to the believers (of Islamic Monotheism).

(78) Allah is the Light of the heavens and the earth. The parable of His Light is as (if there were) a niche and within it a lamp: the lamp is in a glass, the glass as it were a brilliant star, lit from a blessed tree, an olive, neither of the east (i.e. neither it gets sun-rays only in the morning) nor of the west (i.e. nor it gets sun-rays only in the afternoon, but it is exposed to the sun all day long), whose oil would almost glow forth (of itself), though no fire touched it. Light upon Light! Allah guides to His Light whom He wills. And Allah sets forth parables for mankind, and Allah is All-Knower of everything.

(79) Men whom neither trade nor sale (business) diverts from the Remembrance of Allah (with heart and tongue), nor from performing As-Salat (Iqamat-as-Salat), nor from giving the Zakat. They fear a Day when hearts and eyes will be overturned (out of the horror of the torment of the Day of Resurrection).

(80) Yet they have taken besides Him other alihah (gods) who created nothing but are themselves created, and possess neither harm nor benefit for themselves, and possess no power (of causing) death, nor (of giving) life, nor of raising the dead.
