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

(81) Have you not seen those who were forbidden to hold secret counsels, and afterwards returned to that which they had been forbidden, and conspired together for sin and wrong doing and disobedience to the Messenger (Muhammad صلى الله عليه وسلم). And when they come to you, they greet you with a greeting wherewith Allah greets you not, and say within themselves: "Why should Allah punish us not for what we say?" Hell will be sufficient for them; they will burn therein. And worst indeed is that destination!

(82) But those who disbelieved (in the Oneness of Allah - Islamic Monotheism) and denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they will be the dwellers of the Fire, to dwell therein forever. And worst indeed is that destination .

(83) (And has also sent to you) a Messenger (Muhammad صلى الله عليه وسلم), who recites to you the Verses of Allah (the Qur'an) containing clear explanations, that He may take out those who believe and do righteous good deeds, from the darkness (of polytheism and disbelief) to the light (of Islamic Monotheism). And whosoever believes in Allah and performs righteous good deeds, He will admit him into Gardens under which rivers flow (Paradise) to dwell therein forever. Allah has indeed granted for him an excellent provision.

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

(85) And for those who disbelieve in their Lord (Allah) is the torment of Hell, and worst indeed is that destination.
