The root ح ج ر (ḥ-j-r) in the Quran

فَإِن لَّمْ تَفْعَلُوا۟ وَلَن تَفْعَلُوا۟ فَٱتَّقُوا۟ ٱلنَّارَ ٱلَّتِى وَقُودُهَا ٱلنَّاسُ وَٱلْحِجَارَةُ أُعِدَّتْ لِلْكَٰفِرِينَ ۝٢٤

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.

وَإِذِ ٱسْتَسْقَىٰ مُوسَىٰ لِقَوْمِهِۦ فَقُلْنَا ٱضْرِب بِّعَصَاكَ ٱلْحَجَرَ فَٱنفَجَرَتْ مِنْهُ ٱثْنَتَا عَشْرَةَ عَيْنًا قَدْ عَلِمَ كُلُّ أُنَاسٍ مَّشْرَبَهُمْ كُلُوا۟ وَٱشْرَبُوا۟ مِن رِّزْقِ ٱللَّهِ وَلَا تَعْثَوْا۟ فِى ٱلْأَرْضِ مُفْسِدِينَ ۝٦٠

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."

ثُمَّ قَسَتْ قُلُوبُكُم مِّنۢ بَعْدِ ذَٰلِكَ فَهِىَ كَٱلْحِجَارَةِ أَوْ أَشَدُّ قَسْوَةً وَإِنَّ مِنَ ٱلْحِجَارَةِ لَمَا يَتَفَجَّرُ مِنْهُ ٱلْأَنْهَٰرُ وَإِنَّ مِنْهَا لَمَا يَشَّقَّقُ فَيَخْرُجُ مِنْهُ ٱلْمَآءُ وَإِنَّ مِنْهَا لَمَا يَهْبِطُ مِنْ خَشْيَةِ ٱللَّهِ وَمَا ٱللَّهُ بِغَٰفِلٍ عَمَّا تَعْمَلُونَ ۝٧٤

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.

حُرِّمَتْ عَلَيْكُمْ أُمَّهَٰتُكُمْ وَبَنَاتُكُمْ وَأَخَوَٰتُكُمْ وَعَمَّٰتُكُمْ وَخَٰلَٰتُكُمْ وَبَنَاتُ ٱلْأَخِ وَبَنَاتُ ٱلْأُخْتِ وَأُمَّهَٰتُكُمُ ٱلَّٰتِىٓ أَرْضَعْنَكُمْ وَأَخَوَٰتُكُم مِّنَ ٱلرَّضَٰعَةِ وَأُمَّهَٰتُ نِسَآئِكُمْ وَرَبَٰٓئِبُكُمُ ٱلَّٰتِى فِى حُجُورِكُم مِّن نِّسَآئِكُمُ ٱلَّٰتِى دَخَلْتُم بِهِنَّ فَإِن لَّمْ تَكُونُوا۟ دَخَلْتُم بِهِنَّ فَلَا جُنَاحَ عَلَيْكُمْ وَحَلَٰٓئِلُ أَبْنَآئِكُمُ ٱلَّذِينَ مِنْ أَصْلَٰبِكُمْ وَأَن تَجْمَعُوا۟ بَيْنَ ٱلْأُخْتَيْنِ إِلَّا مَا قَدْ سَلَفَ إِنَّ ٱللَّهَ كَانَ غَفُورًا رَّحِيمًا ۝٢٣

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.

وَقَالُوا۟ هَٰذِهِۦٓ أَنْعَٰمٌ وَحَرْثٌ حِجْرٌ لَّا يَطْعَمُهَآ إِلَّا مَن نَّشَآءُ بِزَعْمِهِمْ وَأَنْعَٰمٌ حُرِّمَتْ ظُهُورُهَا وَأَنْعَٰمٌ لَّا يَذْكُرُونَ ٱسْمَ ٱللَّهِ عَلَيْهَا ٱفْتِرَآءً عَلَيْهِ سَيَجْزِيهِم بِمَا كَانُوا۟ يَفْتَرُونَ ۝١٣٨

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.

وَقَطَّعْنَٰهُمُ ٱثْنَتَىْ عَشْرَةَ أَسْبَاطًا أُمَمًا وَأَوْحَيْنَآ إِلَىٰ مُوسَىٰٓ إِذِ ٱسْتَسْقَىٰهُ قَوْمُهُۥٓ أَنِ ٱضْرِب بِّعَصَاكَ ٱلْحَجَرَ فَٱنۢبَجَسَتْ مِنْهُ ٱثْنَتَا عَشْرَةَ عَيْنًا قَدْ عَلِمَ كُلُّ أُنَاسٍ مَّشْرَبَهُمْ وَظَلَّلْنَا عَلَيْهِمُ ٱلْغَمَٰمَ وَأَنزَلْنَا عَلَيْهِمُ ٱلْمَنَّ وَٱلسَّلْوَىٰ كُلُوا۟ مِن طَيِّبَٰتِ مَا رَزَقْنَٰكُمْ وَمَا ظَلَمُونَا وَلَٰكِن كَانُوٓا۟ أَنفُسَهُمْ يَظْلِمُونَ ۝١٦٠

And We divided them into twelve descendant tribes [as distinct] nations. And We inspired to Moses when his people implored him for water, "Strike with your staff the stone," and there gushed forth from it twelve springs. Every people [i.e., tribe] knew its watering place. And We shaded them with clouds and sent down upon them manna and quails, [saying], "Eat from the good things with which We have provided you." And they wronged Us not, but they were [only] wronging themselves.

وَإِذْ قَالُوا۟ ٱللَّهُمَّ إِن كَانَ هَٰذَا هُوَ ٱلْحَقَّ مِنْ عِندِكَ فَأَمْطِرْ عَلَيْنَا حِجَارَةً مِّنَ ٱلسَّمَآءِ أَوِ ٱئْتِنَا بِعَذَابٍ أَلِيمٍ ۝٣٢

And [remember] when they said, "O Allāh, if this should be the truth from You, then rain down upon us stones from the sky or bring us a painful punishment."

فَلَمَّا جَآءَ أَمْرُنَا جَعَلْنَا عَٰلِيَهَا سَافِلَهَا وَأَمْطَرْنَا عَلَيْهَا حِجَارَةً مِّن سِجِّيلٍ مَّنضُودٍ ۝٨٢

So when Our command came, We made the highest part [of the city] its lowest and rained upon them stones of layered hard clay, [which were]

فَجَعَلْنَا عَٰلِيَهَا سَافِلَهَا وَأَمْطَرْنَا عَلَيْهِمْ حِجَارَةً مِّن سِجِّيلٍ ۝٧٤

And We made the highest part [of the city] its lowest and rained upon them stones of hard clay.

وَلَقَدْ كَذَّبَ أَصْحَٰبُ ٱلْحِجْرِ ٱلْمُرْسَلِينَ ۝٨٠

And certainly did the companions of al-Ḥijr [i.e., the Thamūd] deny the messengers.

قُلْ كُونُوا۟ حِجَارَةً أَوْ حَدِيدًا ۝٥٠

Say, "Be you stones or iron

يَوْمَ يَرَوْنَ ٱلْمَلَٰٓئِكَةَ لَا بُشْرَىٰ يَوْمَئِذٍ لِّلْمُجْرِمِينَ وَيَقُولُونَ حِجْرًا مَّحْجُورًا ۝٢٢

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."

وَهُوَ ٱلَّذِى مَرَجَ ٱلْبَحْرَيْنِ هَٰذَا عَذْبٌ فُرَاتٌ وَهَٰذَا مِلْحٌ أُجَاجٌ وَجَعَلَ بَيْنَهُمَا بَرْزَخًا وَحِجْرًا مَّحْجُورًا ۝٥٣

And it is He who has released [simultaneously] the two seas [i.e., bodies of water], one fresh and sweet and one salty and bitter, and He placed between them a barrier and prohibiting partition.

إِنَّ ٱلَّذِينَ يُنَادُونَكَ مِن وَرَآءِ ٱلْحُجُرَٰتِ أَكْثَرُهُمْ لَا يَعْقِلُونَ ۝٤

Indeed, those who call you, [O Muḥammad], from behind the chambers - most of them do not use reason.

لِنُرْسِلَ عَلَيْهِمْ حِجَارَةً مِّن طِينٍ ۝٣٣

To send down upon them stones of clay,

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ قُوٓا۟ أَنفُسَكُمْ وَأَهْلِيكُمْ نَارًا وَقُودُهَا ٱلنَّاسُ وَٱلْحِجَارَةُ عَلَيْهَا مَلَٰٓئِكَةٌ غِلَاظٌ شِدَادٌ لَّا يَعْصُونَ ٱللَّهَ مَآ أَمَرَهُمْ وَيَفْعَلُونَ مَا يُؤْمَرُونَ ۝٦

O you who have believed, protect yourselves and your families from a Fire whose fuel is people and stones, over which are [appointed] angels, harsh and severe; they do not disobey Allāh in what He commands them but do what they are commanded.

هَلْ فِى ذَٰلِكَ قَسَمٌ لِّذِى حِجْرٍ ۝٥

Is there [not] in [all] that an oath [sufficient] for one of perception?

تَرْمِيهِم بِحِجَارَةٍ مِّن سِجِّيلٍ ۝٤

Striking them with stones of hard clay,
