The word(s) "nation" appears 69 time(s) in 63 verse(s) in Quran in Muhammad Pickthal translation.

(21) And know that whatever ye take as spoils of war, lo! a fifth thereof is for Allah, and for the messenger and for the kinsman (who hath need) and orphans and the needy and the wayfarer, if ye believe in Allah and that which We revealed unto Our slave on the Day of Discrimination, the day when the two armies met. And Allah is Able to do all things.

(22) And for every nation there is a messenger. And when their messenger cometh (on the Day of Judgment) it will be judged between them fairly, and they will not be wronged.

(23) Say: I have no power to hurt or benefit myself, save that which Allah willeth. For every nation there is an appointed time. When their time cometh, then they cannot put it off an hour, nor hasten (it).

(24) It was said (unto him): O Noah! Go thou down (from the mountain) with peace from Us and blessings upon thee and some nations (that will spring) from those with thee. (There will be other) nations unto whom We shall give enjoyment a long while and then a painful doom from Us will overtake them.

(25) And his people came unto him, running towards him - and before then they used to commit abominations - He said: O my people! Here are my daughters! They are purer for you. Beware of Allah, and degrade me not in (the person of) my guests. Is there not among you any upright man?

(26) And if thy Lord had willed, He verily would have made mankind one nation, yet they cease not differing,

(27) In their history verily there is a lesson for men of understanding. It is no invented story but a confirmation of the existing (Scripture) and a detailed explanation of everything, and a guidance and a mercy for folk who believe.

(28) Thus We send thee (O Muhammad) unto a nation, before whom other nations have passed away, that thou mayst recite unto them that which We have inspired in thee, while they are disbelievers in the Beneficent. Say: He is my Lord; there is no Allah save Him. In Him do I put my trust and unto Him is my recourse.

(29) No nation can outstrip its term nor can they lag behind.

(30) And verily We have raised in every nation a messenger, (proclaiming): Serve Allah and shun false gods. Then some of them (there were) whom Allah guided, and some of them (there were) upon whom error had just hold. Do but travel in the land and see the nature of the consequence for the deniers!
