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

(21) nay, they reject that of which they have no comprehensive knowledge, and the final sequel of it has not yet come to them; even thus did those before them reject (the truth); see then what was the end of the unjust.

(22) But the chiefs of those who disbelieved from among his people said: We do not consider you but a mortal like ourselves, and we do not see any have followed you but those who are the meanest of us at first thought and we do not see in you any excellence over us; nay, we deem you liars.

(23) And they brought his shirt with false blood upon it. He said: nay, your souls have made the matter light for you, but patience is good and Allah is He Whose help is sought for against what you describe.

(24) He (Yaqoub) said: nay, your souls have made a matter light for you, so patience is good; maybe Allah will bring them all together to me; surely He is the Knowing, the Wise.

(25) And even if there were a Quran with which the mountains were made to pass away, or the earth were travelled over with it, or the dead were made to speak thereby; nay! the commandment is wholly Allah's, Have not yet those who believe known that if Allah please He would certainly guide all the people? And (as for) those who disbelieve, there will not cease to afflict them because of what they do a repelling calamity, or it will alight close by their abodes, until the promise of Allah comes about; surely Allah will not fail in (His) promise.

(26) Is He then Who watches every soul as to what it earns? And yet they give associates to Allah! Say: Give them a name; nay, do you mean to inform Him of what He does not know in the earth, or (do you affirm this) by an outward saying? Rather, their plans are made to appear fair-seeming to those who disbelieve, and they are kept back from the path; and whom Allah makes err, he shall have no guide.

(27) They said: nay, we have come to you with that about which they disputed.

(28) Allah sets forth a parable: (consider) a slave, the property of another, (who) has no power over anything, and one whom We have granted from Ourselves a goodly sustenance so he spends from it secretly and openly; are the two alike? (All) praise is due to Allah! nay, most of them do not know.

(29) And when We change (one) communication for (another) communication, and Allah knows best what He reveals, they say: You are only a forger. nay, most of them do not know.

(30) And they shall be brought before your Lord, standing in ranks: Now certainly you have come to Us as We created you at first. nay, you thought that We had not appointed to you a time of the fulfillment of the promise.
