The Quran root ن ق ص n-q-ṣ

إِلَّا الَّذِينَ عَاهَدتُّم مِّنَ الْمُشْرِكِينَ ثُمَّ لَمْ يَنقُصُوكُمْ شَيْئًا وَلَمْ يُظَاهِرُوا عَلَيْكُمْ أَحَدًا فَأَتِمُّوا إِلَيْهِمْ عَهْدَهُمْ إِلَىٰ مُدَّتِهِمْ إِنَّ اللَّهَ يُحِبُّ الْمُتَّقِينَ ٤

يَنقُصُوكُمْ yanquṣūkum · they have failed you

Excepted are those with whom you made a treaty among the polytheists and then they have not been deficient toward you in anything or supported anyone against you; so complete for them their treaty until their term [has ended]. Indeed, Allāh loves the righteous [who fear Him]. (Surah At-Tawbah, 9:4)

وَإِلَىٰ مَدْيَنَ أَخَاهُمْ شُعَيْبًا قَالَ يَا قَوْمِ اعْبُدُوا اللَّهَ مَا لَكُم مِّنْ إِلَٰهٍ غَيْرُهُ وَلَا تَنقُصُوا الْمِكْيَالَ وَالْمِيزَانَ إِنِّي أَرَاكُم بِخَيْرٍ وَإِنِّي أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍ مُّحِيطٍ ٨٤

تَنقُصُوا tanquṣū · decrease

And to Madyan [We sent] their brother Shuʿayb. He said, "O my people, worship Allāh; you have no deity other than Him. And do not decrease from the measure and the scale. Indeed, I see you in prosperity, but indeed, I fear for you the punishment of an all-encompassing Day. (Surah Hud, 11:84)

وَلَنَبْلُوَنَّكُم بِشَيْءٍ مِّنَ الْخَوْفِ وَالْجُوعِ وَنَقْصٍ مِّنَ الْأَمْوَالِ وَالْأَنفُسِ وَالثَّمَرَاتِ وَبَشِّرِ الصَّابِرِينَ ١٥٥

وَنَقْصٍ wanaqṣin · and loss

And We will surely test you with something of fear and hunger and a loss of wealth and lives and fruits, but give good tidings to the patient, (Surah Al-Baqarah, 2:155)

فَلَا تَكُ فِي مِرْيَةٍ مِّمَّا يَعْبُدُ هَٰؤُلَاءِ مَا يَعْبُدُونَ إِلَّا كَمَا يَعْبُدُ آبَاؤُهُم مِّن قَبْلُ وَإِنَّا لَمُوَفُّوهُمْ نَصِيبَهُمْ غَيْرَ مَنقُوصٍ ١٠٩

مَنقُوصٍ manqūṣin · being diminished

So do not be in doubt, [O Muḥammad], as to what these [polytheists] are worshipping. They worship not except as their fathers worshipped before. And indeed, We will give them their share undiminished. (Surah Hud, 11:109)
