The word(s) "nay" appears 129 time(s) in 124 verse(s) in Quran in Abdullah Yusuf Ali translation.

(81) nay! he has come with the (very) Truth, and he confirms (the Message of) the messengers (before him).

(82) "What! has the Message been sent to him - (Of all persons) among us?"... but they are in doubt concerning My (Own) Message! nay, they have not yet tasted My Punishment!

(83) (The followers shall cry to the misleaders:) "nay, ye (too)! No welcome for you! It is ye who have brought this upon us! Now evil is (this) place to stay in!"

(84) Now, when trouble touches man, he cries to Us: But when We bestow a favour upon him as from Ourselves, he says, "This has been given to me because of a certain knowledge (I have)!" nay, but this is but a trial, but most of them understand not!

(85) nay, the evil results of their Deeds overtook them. And the wrong-doers of this (generation)- the evil results of their Deeds will soon overtake them (too), and they will never be able to frustrate (Our Plan)!

(86) "(The reply will be:) 'nay, but there came to thee my Signs, and thou didst reject them: thou wast Haughty, and became one of those who reject faith!'"

(87) nay, but worship Allah, and be of those who give thanks.

(88) "In derogation of Allah?" They will reply: "They have left us in the lurch: nay, we invoked not, of old, anything (that had real existence)." Thus does Allah leave the Unbelievers to stray.

(89) nay! they say: "We found our fathers following a certain religion, and we do guide ourselves by their footsteps."

(90) They will cry: "O Malik! would that thy Lord put an end to us!" He will say, "nay, but ye shall abide!"
