The word(s) "nay" appears 158 time(s) in 149 verse(s) in Quran in Muhammad Habib Shakir translation.

(71) And those who were deemed weak shall say to those who were proud. nay, (it was) planning by night and day when you told us to disbelieve in Allah and to set up likes with Him. And they shall conceal regret when they shall see the punishment; and We will put shackles on the necks of those who disbelieved; they shall not be requited but what they did.

(72) They shall say: Glory be to Thee! Thou art our Guardian, not they; nay! they worshipped the jinn; most of them were believers in them.

(73) Say: Have you considered your associates which you call upon besides Allah? Show me what part of the earth they have created, or have they any share in the heavens; or, have We given them a book so that they follow a clear argument thereof? nay, the unjust do not hold out promises one to another but only to deceive.

(74) They said: Your evil fortune is with you; what! if you are reminded! nay, you are an extravagant people.

(75) nay! you wonder while they mock,

(76) nay! on that day they shall be submissive.

(77) They shall say: nay, you (yourselves) were not believers;

(78) nay: he has come with the truth and verified the apostles.

(79) nay! those who disbelieve are in self-exaltation and opposition.

(80) Has the reminder been revealed to him from among us? nay! they are in doubt as to My reminder. nay! they have not yet tasted My chastisement!
