The root ن ق ض (n-q-ḍ) in the Quran

ٱلَّذِينَ يَنقُضُونَ عَهْدَ ٱللَّهِ مِنۢ بَعْدِ مِيثَٰقِهِۦ وَيَقْطَعُونَ مَآ أَمَرَ ٱللَّهُ بِهِۦٓ أَن يُوصَلَ وَيُفْسِدُونَ فِى ٱلْأَرْضِ أُو۟لَٰٓئِكَ هُمُ ٱلْخَٰسِرُونَ ۝٢٧

Who break the covenant of Allāh after contracting it and sever that which Allāh has ordered to be joined and cause corruption on earth. It is those who are the losers.

فَبِمَا نَقْضِهِم مِّيثَٰقَهُمْ وَكُفْرِهِم بِـَٔايَٰتِ ٱللَّهِ وَقَتْلِهِمُ ٱلْأَنۢبِيَآءَ بِغَيْرِ حَقٍّ وَقَوْلِهِمْ قُلُوبُنَا غُلْفٌۢ بَلْ طَبَعَ ٱللَّهُ عَلَيْهَا بِكُفْرِهِمْ فَلَا يُؤْمِنُونَ إِلَّا قَلِيلًا ۝١٥٥

And [We cursed them] for their breaking of the covenant and their disbelief in the signs of Allāh and their killing of the prophets without right and their saying, "Our hearts are wrapped" [i.e., sealed against reception]. Rather, Allāh has sealed them because of their disbelief, so they believe not, except for a few.

فَبِمَا نَقْضِهِم مِّيثَٰقَهُمْ لَعَنَّٰهُمْ وَجَعَلْنَا قُلُوبَهُمْ قَٰسِيَةً يُحَرِّفُونَ ٱلْكَلِمَ عَن مَّوَاضِعِهِۦ وَنَسُوا۟ حَظًّا مِّمَّا ذُكِّرُوا۟ بِهِۦ وَلَا تَزَالُ تَطَّلِعُ عَلَىٰ خَآئِنَةٍ مِّنْهُمْ إِلَّا قَلِيلًا مِّنْهُمْ فَٱعْفُ عَنْهُمْ وَٱصْفَحْ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُحْسِنِينَ ۝١٣

So for their breaking of the covenant We cursed them and made their hearts hardened. They distort words from their [proper] places [i.e., usages] and have forgotten a portion of that of which they were reminded. And you will still observe deceit among them, except a few of them. But pardon them and overlook [their misdeeds]. Indeed, Allāh loves the doers of good.

ٱلَّذِينَ عَٰهَدتَّ مِنْهُمْ ثُمَّ يَنقُضُونَ عَهْدَهُمْ فِى كُلِّ مَرَّةٍ وَهُمْ لَا يَتَّقُونَ ۝٥٦

The ones with whom you made a treaty but then they break their pledge every time, and they do not fear Allāh.

ٱلَّذِينَ يُوفُونَ بِعَهْدِ ٱللَّهِ وَلَا يَنقُضُونَ ٱلْمِيثَٰقَ ۝٢٠

Those who fulfill the covenant of Allāh and do not break the contract,

وَٱلَّذِينَ يَنقُضُونَ عَهْدَ ٱللَّهِ مِنۢ بَعْدِ مِيثَٰقِهِۦ وَيَقْطَعُونَ مَآ أَمَرَ ٱللَّهُ بِهِۦٓ أَن يُوصَلَ وَيُفْسِدُونَ فِى ٱلْأَرْضِ أُو۟لَٰٓئِكَ لَهُمُ ٱللَّعْنَةُ وَلَهُمْ سُوٓءُ ٱلدَّارِ ۝٢٥

But those who break the covenant of Allāh after contracting it and sever that which Allāh has ordered to be joined and spread corruption on earth - for them is the curse, and they will have the worst home.

وَأَوْفُوا۟ بِعَهْدِ ٱللَّهِ إِذَا عَٰهَدتُّمْ وَلَا تَنقُضُوا۟ ٱلْأَيْمَٰنَ بَعْدَ تَوْكِيدِهَا وَقَدْ جَعَلْتُمُ ٱللَّهَ عَلَيْكُمْ كَفِيلًا إِنَّ ٱللَّهَ يَعْلَمُ مَا تَفْعَلُونَ ۝٩١

And fulfill the covenant of Allāh when you have taken it, [O believers], and do not break oaths after their confirmation while you have made Allāh, over you, a security [i.e., witness]. Indeed, Allāh knows what you do.

وَلَا تَكُونُوا۟ كَٱلَّتِى نَقَضَتْ غَزْلَهَا مِنۢ بَعْدِ قُوَّةٍ أَنكَٰثًا تَتَّخِذُونَ أَيْمَٰنَكُمْ دَخَلًۢا بَيْنَكُمْ أَن تَكُونَ أُمَّةٌ هِىَ أَرْبَىٰ مِنْ أُمَّةٍ إِنَّمَا يَبْلُوكُمُ ٱللَّهُ بِهِۦ وَلَيُبَيِّنَنَّ لَكُمْ يَوْمَ ٱلْقِيَٰمَةِ مَا كُنتُمْ فِيهِ تَخْتَلِفُونَ ۝٩٢

And do not be like she who untwisted her spun thread after it was strong [by] taking your oaths as [means of] deceit between you because one community is more plentiful [in number or wealth] than another community. Allāh only tries you thereby. And He will surely make clear to you on the Day of Resurrection that over which you used to differ.

ٱلَّذِىٓ أَنقَضَ ظَهْرَكَ ۝٣

Which had weighed upon your back
