The word(s) "no" appears 4045 time(s) in 2612 verse(s) in Quran in Abdullah Yusuf Ali translation.

(731) Hath not the story reached them of those before them?- the People of noah, and 'Ad, and Thamud; the People of Abraham, the men of Midian, and the cities overthrown. To them came their messengers with clear signs. It is not Allah Who wrongs them, but they wrong their own souls.

(732) The Believers, men and women, are protectors one of another: they enjoin what is just, and forbid what is evil: they observe regular prayers, practise regular charity, and obey Allah and His Messenger. On them will Allah pour His mercy: for Allah is Exalted in power, Wise.

(733) They swear by Allah that they said nothing (evil), but indeed they uttered blasphemy, and they did it after accepting Islam; and they meditated a plot which they were unable to carry out: this revenge of theirs was (their) only return for the bounty with which Allah and His Messenger had enriched them! If they repent, it will be best for them; but if they turn back (to their evil ways), Allah will punish them with a grievous penalty in this life and in the Hereafter: They shall have none on earth to protect or help them.

(734) Know they not that Allah doth know their secret (thoughts) and their secret counsels, and that Allah knoweth well all things unseen?

(735) Those who slander such of the believers as give themselves freely to (deeds of) charity, as well as such as can find nothing to give except the fruits of their labour,- and throw ridicule on them,- Allah will throw back their ridicule on them: and they shall have a grievous penalty.

(736) Whether thou ask for their forgiveness, or not, (their sin is unforgivable): if thou ask seventy times for their forgiveness, Allah will not forgive them: because they have rejected Allah and His Messenger: and Allah guideth not those who are perversely rebellious.

(737) Those who were left behind (in the Tabuk expedition) rejoiced in their inaction behind the back of the Messenger of Allah: they hated to strive and fight, with their goods and their persons, in the cause of Allah: they said, "Go not forth in the heat." Say, "The fire of Hell is fiercer in heat." If only they could understand!

(738) If, then, Allah bring thee back to any of them, and they ask thy permission to come out (with thee), say: "Never shall ye come out with me, nor fight an enemy with me: for ye preferred to sit inactive on the first occasion: Then sit ye (now) with those who lag behind."

(739) nor do thou ever pray for any of them that dies, nor stand at his grave; for they rejected Allah and His Messenger, and died in a state of perverse rebellion.

(740) nor let their wealth nor their (following in) sons dazzle thee: Allah's plan is to punish them with these things in this world, and that their souls may perish in their (very) denial of Allah.
