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

(21) And every nation has its appointed term; when their term comes, neither can they delay it nor can they advance it an hour (or a moment).

(22) (Allah) will say: "Enter you in the company of nations who passed away before you, of men and jinn, into the Fire." Every time a new nation enters, it curses its sister nation (that went before) until they will be gathered all together in the Fire. The last of them will say to the first of them: "Our Lord! These misled us, so give them a double torment of the Fire." He will say: "For each one there is double (torment), but you know not."

(23) And We wrote for him on the Tablets the lesson to be drawn from all things and the explanation for all things (and said): Hold unto these with firmness, and enjoin your people to take the better therein. I shall show you the home of Al-Fasiqun (the rebellious, disobedient to Allah).

(24) And We divided them into twelve tribes (as distinct) nations. We revealed to Musa (Moses) when his people asked him for water (saying): "Strike the stone with your stick", and there gushed forth out of it twelve springs, each group knew its own place for water. We shaded them with the clouds and sent down upon them Al-Manna and the quails (saying): "Eat of the good things with which We have provided you." They harmed Us not but they used to harm themselves.

(25) And whoever turns his back to them on such a day - unless it be a stratagem of war, or to retreat to a troop (of his own), - he indeed has drawn upon himself wrath from Allah. And his abode is Hell, and worst indeed is that destination!

(26) O Prophet (Muhammad صلى الله عليه وسلم)! Strive hard against the disbelievers and the hypocrites, and be harsh against them, their abode is Hell, - and worst indeed is that destination.

(27) Verily, in the alternation of the night and the day and in all that Allah has created in the heavens and the earth are Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) for those people who keep their duty to Allah, and fear Him much.

(28) And this Qur'an is not such as could ever be produced by other than Allah (Lord of the heavens and the earth), but it is a confirmation of (the revelation) which was before it [i.e. the Taurat (Torah), and the Injeel (Gospel)], and a full explanation of the Book (i.e. laws, decreed for mankind) - wherein there is no doubt - from the Lord of the 'Alamin (mankind, jinn, and all that exists).

(29) And for every Ummah (a community or a nation) there is a Messenger; when their Messenger comes, the matter will be judged between them with justice, and they will not be wronged.

(30) Say (O Muhammad صلى الله عليه وسلم): "I have no power over any harm or profit to myself except what Allah may will. For every Ummah (a community or a nation), there is a term appointed; when their term comes, neither can they delay it nor can they advance it an hour (or a moment)." (Tafsir Al-Qurtubi).
