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

(51) And We gave them of Our Mercy (a good provision in plenty), and We granted them honour on the tongues (of all the nations, i.e. everybody remembers them with a good praise).

(52) And how many a generation (past nations) have We destroyed before them, who were better in wealth, goods and outward appearance?

(53) That (Manasik- prescribed duties of Hajj is the obligation that mankind owes to Allah), and whoever honours the sacred things of Allah, then that is better for him with his Lord. The cattle are lawful to you, except those (that will be) mentioned to you (as exceptions). So shun the abomination (worshipping) of idol, and shun lying speech (false statements) -

(54) And for every nation We have appointed religious ceremonies, that they may mention the Name of Allah over the beast of cattle that He has given them for food. And your Ilah (God) is One Ilah (God - Allah), so you must submit to Him Alone (in Islam). And (O Muhammad صلى الله عليه وسلم) give glad tidings to the Mukhbitun (those who obey Allah with humility and are humble from among the true believers of Islamic Monotheism),

(55) For every nation We have ordained religious ceremonies [e.g. slaughtering of the cattle during the three days of stay at Mina (Makkah) during the Hajj (pilgrimage)] which they must follow; so let them (the pagans) not dispute with you on the matter (i.e. to eat of the cattle which you slaughter, and not to eat of the cattle which Allah kills by its natural death), but invite them to your Lord. Verily you (O Muhammad صلى الله عليه وسلم) indeed are on the (true) straight guidance (i.e. the true religion of Islamic Monotheism).

(56) And when Our Clear Verses are recited to them, you will notice a denial on the faces of the disbelievers! They are nearly ready to attack with violence those who recite Our Verses to them. Say: "Shall I tell you of something worse than that? The Fire (of Hell) which Allah has promised to those who disbelieved, and worst indeed is that destination!"

(57) No nation can advance their term, nor can they delay it.

(58) Then We sent Our Messengers in succession. Every time there came to a nation their Messenger, they denied him; so We made them follow one another (to destruction), and We made them as Ahadith (the true stories for mankind to learn a lesson from them). So away with a people who believe not!

(59) And it is He Who gives life and causes death, and His is the alternation of night and day. Will you not then understand?

(60) Consider not that the disbelievers can escape in the land. Their abode shall be the Fire - and worst indeed is that destination.
