The word(s) "nay" appears 143 time(s) in 137 verse(s) in Quran in Mohsin Khan translation.

(71) And those who were arrogant will say to those who were deemed weak: "Did we keep you back from guidance after it had come to you? nay, but you were Mujrimun (polytheists, sinners, disbelievers, criminals)."

(72) Those who were deemed weak will say to those who were arrogant: "nay, but it was your plotting by night and day: when you ordered us to disbelieve in Allah and set up rivals to Him!" And each of them (parties) will conceal their own regrets (for disobeying Allah during this worldly life), when they behold the torment. And We shall put iron collars round the necks of those who disbelieved. Are they requited aught except what they used to do?

(73) They (the angels) will say: "Glorified be You! You are our Wali (Lord) instead of them. nay, but they used to worship the jinn; most of them were believers in them."

(74) Say (O Muhammad صلى الله عليه وسلم): "Tell me or inform me (what) do you think about your (so-called) partner-gods to whom you call upon besides Allah? Show me, what they have created of the earth. Or have they any share in the heavens? Or have We given them a Book, so that they act on clear proof therefrom? nay, the Zalimun (polytheists and wrong-doers) promise one another nothing but delusions."

(75) They (Messengers) said: "Your evil omens be with you! (Do you call it "evil omen") because you are admonished? nay, but you are a people Musrifun (transgressing all bounds by committing all kinds of great sins, and by disobeying Allah).

(76) nay, you (O Muhammad صلى الله عليه وسلم) wondered (at their insolence) while they mock (at you and at the Qur'an).

(77) nay, but that Day they shall surrender.

(78) They will reply: "nay, you yourselves were not believers.

(79) "And we had no authority over you. nay! But you were Taghun (transgressing) people (polytheists, and disbelievers).

(80) nay! he (Muhammad صلى الله عليه وسلم) has come with the truth (i.e. Allah's religion - Islamic Monotheism and this Qur'an) and he confirms the Messengers (before him who brought Allah's religion - Islamic Monotheism).
