The word(s) "nation" appears 91 time(s) in 85 verse(s) in Quran in Mohsin Khan translation.

(71) Sad. [These letters (Sad, etc.) are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings]. By the Qur'an full of reminding (explanations and honour for the one who believes in it).

(72) The people of Nuh (Noah) and the Confederates after them denied (their Messengers) before these; and every (disbelieving) nation plotted against their Messenger to seize him, and disputed by means of falsehood to refute therewith the truth. So I seized them (with punishment), and how (terrible) was My punishment!

(73) And if Allah had willed, He could have made them one nation, but He admits whom He wills to His Mercy. And the Zalimun (polytheists and wrong-doers) will have neither a Wali (protector or guardian) nor a helper.

(74) And in the alternation of night and day, and the provision (rain) that Allah sends down from the sky, and revives therewith the earth after its death, and in the turning about of the winds (i.e. sometimes towards the east or north, and sometimes towards the south or west sometimes bringing glad tidings of rain etc., and sometimes bringing the torment), are signs for a people who understand.

(75) And you will see each nation humbled to their knees (kneeling): each nation will be called to its Record (of deeds). This Day you shall be recompensed for what you used to do.

(76) And that He may punish the Munafiqun (hypocrites), men and women, and also the Mushrikun men and women, who think evil thoughts about Allah: for them is a disgraceful torment. And the Anger of Allah is upon them, and He has cursed them and prepared Hell for them - and worst indeed is that destination.

(77) O mankind! We have created you from a male and a female, and made you into nations and tribes, that you may know one another. Verily, the most honourable of you with Allah is that (believer) who has At-Taqwa [i.e. he is one of the Muttaqun (the pious. See V.2:2)]. Verily, Allah is All-Knowing, All-Aware.

(78) Are your disbelievers (O Quraish!) better than these [nations of Nuh (Noah), Lut (Lot), Salih, and the people of Fir'aun (Pharaoh) who were destroyed)? Or have you an immunity (against Our Torment) in the Divine Scriptures?

(79) So this Day no ransom shall be taken from you (hypocrites), nor of those who disbelieved, (in the Oneness of Allah - Islamic Monotheism). Your abode is the Fire. That is your maula (friend - proper place), and worst indeed is that destination.

(80) Verily, those who oppose Allah and His Messenger (Muhammad صلى الله عليه وسلم) will be disgraced, as those before them (among the past nation) were disgraced. And We have sent down clear Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.). And for the disbelievers is a disgracing torment.
