The word(s) "nay" appears 148 time(s) in 143 verse(s) in Quran in Muhammad Pickthal translation.

(41) He said: nay, but your Lord is the Lord of the heavens and the earth, Who created them; and I am of those who testify unto that.

(42) We hasten unto them with good things? nay, but they perceive not.

(43) nay, but their hearts are in ignorance of this (Qur'an), and they have other works, besides, which they are doing;

(44) Or say they: There is a madness in him? nay, but he bringeth them the Truth; and most of them are haters of the Truth.

(45) And if the Truth had followed their desires, verily the heavens and the earth and whosoever is therein had been corrupted. nay, We have brought them their Reminder, but from their Reminder they now turn away.

(46) nay, but they say the like of that which said the men of old;

(47) nay, but We have brought them the Truth, and lo! they are liars.

(48) That I may do right in that which I have left behind! But nay! It is but a word that he speaketh; and behind them is a barrier until the day when they are raised.

(49) Lo! they who spread the slander are a gang among you. Deem it not a bad thing for you; nay, it is good for you. Unto every man of them (will be paid) that which he hath earned of the sin; and as for him among them who had the greater share therein, his will be an awful doom.

(50) Is there in their hearts a disease, or have they doubts, or fear they lest Allah and His messenger should wrong them in judgment? nay, but such are evil-doers.
