The Quran root ح ج ر ḥ-j-r

فَإِن لَّمْ تَفْعَلُوا وَلَن تَفْعَلُوا فَاتَّقُوا النَّارَ الَّتِي وَقُودُهَا النَّاسُ وَالْحِجَارَةُ أُعِدَّتْ لِلْكَافِرِينَ ٢٤

وَالْحِجَارَةُ wal-ḥijāratu · and [the] stones

But if you do not - and you will never be able to - then fear the Fire, whose fuel is people and stones, prepared for the disbelievers. (Surah Al-Baqarah, 2:24)

ثُمَّ قَسَتْ قُلُوبُكُم مِّن بَعْدِ ذَٰلِكَ فَهِيَ كَالْحِجَارَةِ أَوْ أَشَدُّ قَسْوَةً وَإِنَّ مِنَ الْحِجَارَةِ لَمَا يَتَفَجَّرُ مِنْهُ الْأَنْهَارُ وَإِنَّ مِنْهَا لَمَا يَشَّقَّقُ فَيَخْرُجُ مِنْهُ الْمَاءُ وَإِنَّ مِنْهَا لَمَا يَهْبِطُ مِنْ خَشْيَةِ اللَّهِ وَمَا اللَّهُ بِغَافِلٍ عَمَّا تَعْمَلُونَ ٧٤

كَالْحِجَارَةِ kal-ḥijārati · (became) like [the] stones

Then your hearts became hardened after that, being like stones or even harder. For indeed, there are stones from which rivers burst forth, and there are some of them that split open and water comes out, and there are some of them that fall down for fear of Allāh. And Allāh is not unaware of what you do. (Surah Al-Baqarah, 2:74)

وَقَالُوا هَٰذِهِ أَنْعَامٌ وَحَرْثٌ حِجْرٌ لَّا يَطْعَمُهَا إِلَّا مَن نَّشَاءُ بِزَعْمِهِمْ وَأَنْعَامٌ حُرِّمَتْ ظُهُورُهَا وَأَنْعَامٌ لَّا يَذْكُرُونَ اسْمَ اللَّهِ عَلَيْهَا افْتِرَاءً عَلَيْهِ سَيَجْزِيهِم بِمَا كَانُوا يَفْتَرُونَ ١٣٨

حِجْرٌ ḥij'run · forbidden

And they say, "These animals and crops are forbidden; no one may eat from them except whom we will," by their claim. And there are those [camels] whose backs are forbidden [by them] and those upon which the name of Allāh is not mentioned - [all of this] an invention of untruth about Him. He will punish them for what they were inventing. (Surah Al-An'am, 6:138)

وَإِذِ اسْتَسْقَىٰ مُوسَىٰ لِقَوْمِهِ فَقُلْنَا اضْرِب بِّعَصَاكَ الْحَجَرَ فَانفَجَرَتْ مِنْهُ اثْنَتَا عَشْرَةَ عَيْنًا قَدْ عَلِمَ كُلُّ أُنَاسٍ مَّشْرَبَهُمْ كُلُوا وَاشْرَبُوا مِن رِّزْقِ اللَّهِ وَلَا تَعْثَوْا فِي الْأَرْضِ مُفْسِدِينَ ٦٠

الْحَجَرَ l-ḥajara · the stone

And [recall] when Moses prayed for water for his people, so We said, "Strike with your staff the stone." And there gushed forth from it twelve springs, and every people [i.e., tribe] knew its watering place. "Eat and drink from the provision of Allāh, and do not commit abuse on the earth, spreading corruption." (Surah Al-Baqarah, 2:60)

يَوْمَ يَرَوْنَ الْمَلَائِكَةَ لَا بُشْرَىٰ يَوْمَئِذٍ لِّلْمُجْرِمِينَ وَيَقُولُونَ حِجْرًا مَّحْجُورًا ٢٢

مَّحْجُورًا maḥjūran · forbidden

The day they see the angels - no good tidings will there be that day for the criminals, and [the angels] will say, "Prevented and inaccessible." (Surah Al-Furqan, 25:22)

حُرِّمَتْ عَلَيْكُمْ أُمَّهَاتُكُمْ وَبَنَاتُكُمْ وَأَخَوَاتُكُمْ وَعَمَّاتُكُمْ وَخَالَاتُكُمْ وَبَنَاتُ الْأَخِ وَبَنَاتُ الْأُخْتِ وَأُمَّهَاتُكُمُ اللَّاتِي أَرْضَعْنَكُمْ وَأَخَوَاتُكُم مِّنَ الرَّضَاعَةِ وَأُمَّهَاتُ نِسَائِكُمْ وَرَبَائِبُكُمُ اللَّاتِي فِي حُجُورِكُم مِّن نِّسَائِكُمُ اللَّاتِي دَخَلْتُم بِهِنَّ فَإِن لَّمْ تَكُونُوا دَخَلْتُم بِهِنَّ فَلَا جُنَاحَ عَلَيْكُمْ وَحَلَائِلُ أَبْنَائِكُمُ الَّذِينَ مِنْ أَصْلَابِكُمْ وَأَن تَجْمَعُوا بَيْنَ الْأُخْتَيْنِ إِلَّا مَا قَدْ سَلَفَ إِنَّ اللَّهَ كَانَ غَفُورًا رَّحِيمًا ٢٣

حُجُورِكُم ḥujūrikum · your guardianship

Prohibited to you [for marriage] are your mothers, your daughters, your sisters, your father's sisters, your mother's sisters, your brother's daughters, your sister's daughters, your [milk] mothers who nursed you, your sisters through nursing, your wives' mothers, and your step-daughters under your guardianship [born] of your wives unto whom you have gone in. But if you have not gone in unto them, there is no sin upon you. And [also prohibited are] the wives of your sons who are from your [own] loins, and that you take [in marriage] two sisters simultaneously, except for what has already occurred. Indeed, Allāh is ever Forgiving and Merciful. (Surah An-Nisa, 4:23)
