The root ن ج م (n-j-m) in the Quran

وَهُوَ ٱلَّذِى جَعَلَ لَكُمُ ٱلنُّجُومَ لِتَهْتَدُوا۟ بِهَا فِى ظُلُمَٰتِ ٱلْبَرِّ وَٱلْبَحْرِ قَدْ فَصَّلْنَا ٱلْـَٔايَٰتِ لِقَوْمٍ يَعْلَمُونَ ۝٩٧

And it is He who placed for you the stars that you may be guided by them through the darknesses of the land and sea. We have detailed the signs for a people who know.

إِنَّ رَبَّكُمُ ٱللَّهُ ٱلَّذِى خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ فِى سِتَّةِ أَيَّامٍ ثُمَّ ٱسْتَوَىٰ عَلَى ٱلْعَرْشِ يُغْشِى ٱلَّيْلَ ٱلنَّهَارَ يَطْلُبُهُۥ حَثِيثًا وَٱلشَّمْسَ وَٱلْقَمَرَ وَٱلنُّجُومَ مُسَخَّرَٰتٍۭ بِأَمْرِهِۦٓ أَلَا لَهُ ٱلْخَلْقُ وَٱلْأَمْرُ تَبَارَكَ ٱللَّهُ رَبُّ ٱلْعَٰلَمِينَ ۝٥٤

Indeed, your Lord is Allāh, who created the heavens and earth in six days and then established Himself above the Throne. He covers the night with the day, [another night] chasing it rapidly; and [He created] the sun, the moon, and the stars, subjected by His command. Unquestionably, His is the creation and the command; blessed is Allāh, Lord of the worlds.

وَسَخَّرَ لَكُمُ ٱلَّيْلَ وَٱلنَّهَارَ وَٱلشَّمْسَ وَٱلْقَمَرَ وَٱلنُّجُومُ مُسَخَّرَٰتٌۢ بِأَمْرِهِۦٓ إِنَّ فِى ذَٰلِكَ لَـَٔايَٰتٍ لِّقَوْمٍ يَعْقِلُونَ ۝١٢

And He has subjected for you the night and day and the sun and moon, and the stars are subjected by His command. Indeed in that are signs for a people who reason.

وَعَلَٰمَٰتٍ وَبِٱلنَّجْمِ هُمْ يَهْتَدُونَ ۝١٦

And landmarks. And by the stars they are [also] guided.

أَلَمْ تَرَ أَنَّ ٱللَّهَ يَسْجُدُ لَهُۥ مَن فِى ٱلسَّمَٰوَٰتِ وَمَن فِى ٱلْأَرْضِ وَٱلشَّمْسُ وَٱلْقَمَرُ وَٱلنُّجُومُ وَٱلْجِبَالُ وَٱلشَّجَرُ وَٱلدَّوَآبُّ وَكَثِيرٌ مِّنَ ٱلنَّاسِ وَكَثِيرٌ حَقَّ عَلَيْهِ ٱلْعَذَابُ وَمَن يُهِنِ ٱللَّهُ فَمَا لَهُۥ مِن مُّكْرِمٍ إِنَّ ٱللَّهَ يَفْعَلُ مَا يَشَآءُ ۝١٨

Do you not see [i.e., know] that to Allāh prostrates whoever is in the heavens and whoever is on the earth and the sun, the moon, the stars, the mountains, the trees, the moving creatures and many of the people? But upon many the punishment has been justified. And he whom Allāh humiliates - for him there is no bestower of honor. Indeed, Allāh does what He wills.

فَنَظَرَ نَظْرَةً فِى ٱلنُّجُومِ ۝٨٨

And he cast a look at the stars

وَمِنَ ٱلَّيْلِ فَسَبِّحْهُ وَإِدْبَٰرَ ٱلنُّجُومِ ۝٤٩

And in a part of the night exalt Him and after [the setting of] the stars.

وَٱلنَّجْمِ إِذَا هَوَىٰ ۝١

By the star when it descends,

وَٱلنَّجْمُ وَٱلشَّجَرُ يَسْجُدَانِ ۝٦

And the stars and trees prostrate.

فَلَآ أُقْسِمُ بِمَوَٰقِعِ ٱلنُّجُومِ ۝٧٥

Then I swear by the setting of the stars,

فَإِذَا ٱلنُّجُومُ طُمِسَتْ ۝٨

So when the stars are obliterated

وَإِذَا ٱلنُّجُومُ ٱنكَدَرَتْ ۝٢

And when the stars fall, dispersing,

ٱلنَّجْمُ ٱلثَّاقِبُ ۝٣

It is the piercing star.
