The root ح ر ج (ḥ-r-j) in the Quran

فَلَا وَرَبِّكَ لَا يُؤْمِنُونَ حَتَّىٰ يُحَكِّمُوكَ فِيمَا شَجَرَ بَيْنَهُمْ ثُمَّ لَا يَجِدُوا۟ فِىٓ أَنفُسِهِمْ حَرَجًا مِّمَّا قَضَيْتَ وَيُسَلِّمُوا۟ تَسْلِيمًا ۝٦٥

But no, by your Lord, they will not [truly] believe until they make you, [O Muḥammad], judge concerning that over which they dispute among themselves and then find within themselves no discomfort from what you have judged and submit in [full, willing] submission.

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا قُمْتُمْ إِلَى ٱلصَّلَوٰةِ فَٱغْسِلُوا۟ وُجُوهَكُمْ وَأَيْدِيَكُمْ إِلَى ٱلْمَرَافِقِ وَٱمْسَحُوا۟ بِرُءُوسِكُمْ وَأَرْجُلَكُمْ إِلَى ٱلْكَعْبَيْنِ وَإِن كُنتُمْ جُنُبًا فَٱطَّهَّرُوا۟ وَإِن كُنتُم مَّرْضَىٰٓ أَوْ عَلَىٰ سَفَرٍ أَوْ جَآءَ أَحَدٌ مِّنكُم مِّنَ ٱلْغَآئِطِ أَوْ لَٰمَسْتُمُ ٱلنِّسَآءَ فَلَمْ تَجِدُوا۟ مَآءً فَتَيَمَّمُوا۟ صَعِيدًا طَيِّبًا فَٱمْسَحُوا۟ بِوُجُوهِكُمْ وَأَيْدِيكُم مِّنْهُ مَا يُرِيدُ ٱللَّهُ لِيَجْعَلَ عَلَيْكُم مِّنْ حَرَجٍ وَلَٰكِن يُرِيدُ لِيُطَهِّرَكُمْ وَلِيُتِمَّ نِعْمَتَهُۥ عَلَيْكُمْ لَعَلَّكُمْ تَشْكُرُونَ ۝٦

O you who have believed, when you rise to [perform] prayer, wash your faces and your forearms to the elbows and wipe over your heads and wash your feet to the ankles. And if you are in a state of janābah, then purify yourselves. But if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women and do not find water, then seek clean earth and wipe over your faces and hands with it. Allāh does not intend to make difficulty for you, but He intends to purify you and complete His favor upon you that you may be grateful.

فَمَن يُرِدِ ٱللَّهُ أَن يَهْدِيَهُۥ يَشْرَحْ صَدْرَهُۥ لِلْإِسْلَٰمِ وَمَن يُرِدْ أَن يُضِلَّهُۥ يَجْعَلْ صَدْرَهُۥ ضَيِّقًا حَرَجًا كَأَنَّمَا يَصَّعَّدُ فِى ٱلسَّمَآءِ كَذَٰلِكَ يَجْعَلُ ٱللَّهُ ٱلرِّجْسَ عَلَى ٱلَّذِينَ لَا يُؤْمِنُونَ ۝١٢٥

So whoever Allāh wants to guide - He expands his breast to [contain] Islām; and whoever He wants to send astray - He makes his breast tight and constricted as though he were climbing into the sky. Thus does Allāh place defilement upon those who do not believe.

كِتَٰبٌ أُنزِلَ إِلَيْكَ فَلَا يَكُن فِى صَدْرِكَ حَرَجٌ مِّنْهُ لِتُنذِرَ بِهِۦ وَذِكْرَىٰ لِلْمُؤْمِنِينَ ۝٢

[This is] a Book revealed to you, [O Muḥammad] - so let there not be in your breast distress therefrom - that you may warn thereby and as a reminder to the believers.

لَّيْسَ عَلَى ٱلضُّعَفَآءِ وَلَا عَلَى ٱلْمَرْضَىٰ وَلَا عَلَى ٱلَّذِينَ لَا يَجِدُونَ مَا يُنفِقُونَ حَرَجٌ إِذَا نَصَحُوا۟ لِلَّهِ وَرَسُولِهِۦ مَا عَلَى ٱلْمُحْسِنِينَ مِن سَبِيلٍ وَٱللَّهُ غَفُورٌ رَّحِيمٌ ۝٩١

There is not upon the weak or upon the ill or upon those who do not find anything to spend any discomfort [i.e., guilt] when they are sincere to Allāh and His Messenger. There is not upon the doers of good any cause [for blame]. And Allāh is Forgiving and Merciful.

وَجَٰهِدُوا۟ فِى ٱللَّهِ حَقَّ جِهَادِهِۦ هُوَ ٱجْتَبَىٰكُمْ وَمَا جَعَلَ عَلَيْكُمْ فِى ٱلدِّينِ مِنْ حَرَجٍ مِّلَّةَ أَبِيكُمْ إِبْرَٰهِيمَ هُوَ سَمَّىٰكُمُ ٱلْمُسْلِمِينَ مِن قَبْلُ وَفِى هَٰذَا لِيَكُونَ ٱلرَّسُولُ شَهِيدًا عَلَيْكُمْ وَتَكُونُوا۟ شُهَدَآءَ عَلَى ٱلنَّاسِ فَأَقِيمُوا۟ ٱلصَّلَوٰةَ وَءَاتُوا۟ ٱلزَّكَوٰةَ وَٱعْتَصِمُوا۟ بِٱللَّهِ هُوَ مَوْلَىٰكُمْ فَنِعْمَ ٱلْمَوْلَىٰ وَنِعْمَ ٱلنَّصِيرُ ۝٧٨

And strive for Allāh with the striving due to Him. He has chosen you and has not placed upon you in the religion any difficulty. [It is] the religion of your father, Abraham. He [i.e., Allāh] named you "Muslims" before [in former scriptures] and in this [revelation] that the Messenger may be a witness over you and you may be witnesses over the people. So establish prayer and give zakāh and hold fast to Allāh. He is your protector; and excellent is the protector, and excellent is the helper.

لَّيْسَ عَلَى ٱلْأَعْمَىٰ حَرَجٌ وَلَا عَلَى ٱلْأَعْرَجِ حَرَجٌ وَلَا عَلَى ٱلْمَرِيضِ حَرَجٌ وَلَا عَلَىٰٓ أَنفُسِكُمْ أَن تَأْكُلُوا۟ مِنۢ بُيُوتِكُمْ أَوْ بُيُوتِ ءَابَآئِكُمْ أَوْ بُيُوتِ أُمَّهَٰتِكُمْ أَوْ بُيُوتِ إِخْوَٰنِكُمْ أَوْ بُيُوتِ أَخَوَٰتِكُمْ أَوْ بُيُوتِ أَعْمَٰمِكُمْ أَوْ بُيُوتِ عَمَّٰتِكُمْ أَوْ بُيُوتِ أَخْوَٰلِكُمْ أَوْ بُيُوتِ خَٰلَٰتِكُمْ أَوْ مَا مَلَكْتُم مَّفَاتِحَهُۥٓ أَوْ صَدِيقِكُمْ لَيْسَ عَلَيْكُمْ جُنَاحٌ أَن تَأْكُلُوا۟ جَمِيعًا أَوْ أَشْتَاتًا فَإِذَا دَخَلْتُم بُيُوتًا فَسَلِّمُوا۟ عَلَىٰٓ أَنفُسِكُمْ تَحِيَّةً مِّنْ عِندِ ٱللَّهِ مُبَٰرَكَةً طَيِّبَةً كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَكُمُ ٱلْـَٔايَٰتِ لَعَلَّكُمْ تَعْقِلُونَ ۝٦١

There is not upon the blind [any] constraint nor upon the lame constraint nor upon the ill constraint nor upon yourselves when you eat from your [own] houses or the houses of your fathers or the houses of your mothers or the houses of your brothers or the houses of your sisters or the houses of your father's brothers or the houses of your father's sisters or the houses of your mother's brothers or the houses of your mother's sisters or [from houses] whose keys you possess or [from the house] of your friend. There is no blame upon you whether you eat together or separately. But when you enter houses, give greetings of peace upon each other - a greeting from Allāh, blessed and good. Thus does Allāh make clear to you the verses [of ordinance] that you may understand.

وَإِذْ تَقُولُ لِلَّذِىٓ أَنْعَمَ ٱللَّهُ عَلَيْهِ وَأَنْعَمْتَ عَلَيْهِ أَمْسِكْ عَلَيْكَ زَوْجَكَ وَٱتَّقِ ٱللَّهَ وَتُخْفِى فِى نَفْسِكَ مَا ٱللَّهُ مُبْدِيهِ وَتَخْشَى ٱلنَّاسَ وَٱللَّهُ أَحَقُّ أَن تَخْشَىٰهُ فَلَمَّا قَضَىٰ زَيْدٌ مِّنْهَا وَطَرًا زَوَّجْنَٰكَهَا لِكَىْ لَا يَكُونَ عَلَى ٱلْمُؤْمِنِينَ حَرَجٌ فِىٓ أَزْوَٰجِ أَدْعِيَآئِهِمْ إِذَا قَضَوْا۟ مِنْهُنَّ وَطَرًا وَكَانَ أَمْرُ ٱللَّهِ مَفْعُولًا ۝٣٧

And [remember, O Muḥammad], when you said to the one on whom Allāh bestowed favor and you bestowed favor, "Keep your wife and fear Allāh," while you concealed within yourself that which Allāh is to disclose. And you feared the people, while Allāh has more right that you fear Him. So when Zayd had no longer any need for her, We married her to you in order that there not be upon the believers any discomfort [i.e., guilt] concerning the wives of their claimed [i.e., adopted] sons when they no longer have need of them. And ever is the command [i.e., decree] of Allāh accomplished.

مَّا كَانَ عَلَى ٱلنَّبِىِّ مِنْ حَرَجٍ فِيمَا فَرَضَ ٱللَّهُ لَهُۥ سُنَّةَ ٱللَّهِ فِى ٱلَّذِينَ خَلَوْا۟ مِن قَبْلُ وَكَانَ أَمْرُ ٱللَّهِ قَدَرًا مَّقْدُورًا ۝٣٨

There is not to be upon the Prophet any discomfort concerning that which Allāh has imposed upon him. [This is] the established way of Allāh with those [prophets] who have passed on before. And ever is the command of Allāh a destiny decreed.

يَٰٓأَيُّهَا ٱلنَّبِىُّ إِنَّآ أَحْلَلْنَا لَكَ أَزْوَٰجَكَ ٱلَّٰتِىٓ ءَاتَيْتَ أُجُورَهُنَّ وَمَا مَلَكَتْ يَمِينُكَ مِمَّآ أَفَآءَ ٱللَّهُ عَلَيْكَ وَبَنَاتِ عَمِّكَ وَبَنَاتِ عَمَّٰتِكَ وَبَنَاتِ خَالِكَ وَبَنَاتِ خَٰلَٰتِكَ ٱلَّٰتِى هَاجَرْنَ مَعَكَ وَٱمْرَأَةً مُّؤْمِنَةً إِن وَهَبَتْ نَفْسَهَا لِلنَّبِىِّ إِنْ أَرَادَ ٱلنَّبِىُّ أَن يَسْتَنكِحَهَا خَالِصَةً لَّكَ مِن دُونِ ٱلْمُؤْمِنِينَ قَدْ عَلِمْنَا مَا فَرَضْنَا عَلَيْهِمْ فِىٓ أَزْوَٰجِهِمْ وَمَا مَلَكَتْ أَيْمَٰنُهُمْ لِكَيْلَا يَكُونَ عَلَيْكَ حَرَجٌ وَكَانَ ٱللَّهُ غَفُورًا رَّحِيمًا ۝٥٠

O Prophet, indeed We have made lawful to you your wives to whom you have given their due compensation and those your right hand possesses from what Allāh has returned to you [of captives] and the daughters of your paternal uncles and the daughters of your paternal aunts and the daughters of your maternal uncles and the daughters of your maternal aunts who emigrated with you and a believing woman if she gives herself to the Prophet [and] if the Prophet wishes to marry her; [this is] only for you, excluding the [other] believers. We certainly know what We have made obligatory upon them concerning their wives and those their right hands possess, [but this is for you] in order that there will be upon you no discomfort [i.e., difficulty]. And ever is Allāh Forgiving and Merciful.

لَّيْسَ عَلَى ٱلْأَعْمَىٰ حَرَجٌ وَلَا عَلَى ٱلْأَعْرَجِ حَرَجٌ وَلَا عَلَى ٱلْمَرِيضِ حَرَجٌ وَمَن يُطِعِ ٱللَّهَ وَرَسُولَهُۥ يُدْخِلْهُ جَنَّٰتٍ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ وَمَن يَتَوَلَّ يُعَذِّبْهُ عَذَابًا أَلِيمًا ۝١٧

There is not upon the blind any guilt or upon the lame any guilt or upon the ill any guilt [for remaining behind]. And whoever obeys Allāh and His Messenger - He will admit him to gardens beneath which rivers flow; but whoever turns away - He will punish him with a painful punishment.
