The Quran root ح ج ج ḥ-j-j

وَإِذَا لَقُوا الَّذِينَ آمَنُوا قَالُوا آمَنَّا وَإِذَا خَلَا بَعْضُهُمْ إِلَىٰ بَعْضٍ قَالُوا أَتُحَدِّثُونَهُم بِمَا فَتَحَ اللَّهُ عَلَيْكُمْ لِيُحَاجُّوكُم بِهِ عِندَ رَبِّكُمْ أَفَلَا تَعْقِلُونَ ٧٦

لِيُحَاجُّوكُم liyuḥājjūkum · so that they argue with you

And when they meet those who believe, they say, "We have believed"; but when they are alone with one another, they say, "Do you talk to them about what Allāh has revealed to you so they can argue with you about it before your Lord?" Then will you not reason? (Surah Al-Baqarah, 2:76)

قُلْ أَتُحَاجُّونَنَا فِي اللَّهِ وَهُوَ رَبُّنَا وَرَبُّكُمْ وَلَنَا أَعْمَالُنَا وَلَكُمْ أَعْمَالُكُمْ وَنَحْنُ لَهُ مُخْلِصُونَ ١٣٩

أَتُحَاجُّونَنَا atuḥājjūnanā · Do you argue with us

Say, [O Muḥammad], "Do you argue with us about Allāh while He is our Lord and your Lord? For us are our deeds, and for you are your deeds. And we are sincere [in deed and intention] to Him." (Surah Al-Baqarah, 2:139)

يَسْأَلُونَكَ عَنِ الْأَهِلَّةِ قُلْ هِيَ مَوَاقِيتُ لِلنَّاسِ وَالْحَجِّ وَلَيْسَ الْبِرُّ بِأَن تَأْتُوا الْبُيُوتَ مِن ظُهُورِهَا وَلَٰكِنَّ الْبِرَّ مَنِ اتَّقَىٰ وَأْتُوا الْبُيُوتَ مِنْ أَبْوَابِهَا وَاتَّقُوا اللَّهَ لَعَلَّكُمْ تُفْلِحُونَ ١٨٩

وَالْحَجِّ wal-ḥaji · and (for) the Hajj

They ask you, [O Muḥammad], about the crescent moons. Say, "They are measurements of time for the people and for ḥajj [pilgrimage]." And it is not righteousness to enter houses from the back, but righteousness is [in] one who fears Allāh. And enter houses from their doors. And fear Allāh that you may succeed. (Surah Al-Baqarah, 2:189)

وَمِنْ حَيْثُ خَرَجْتَ فَوَلِّ وَجْهَكَ شَطْرَ الْمَسْجِدِ الْحَرَامِ وَحَيْثُ مَا كُنتُمْ فَوَلُّوا وُجُوهَكُمْ شَطْرَهُ لِئَلَّا يَكُونَ لِلنَّاسِ عَلَيْكُمْ حُجَّةٌ إِلَّا الَّذِينَ ظَلَمُوا مِنْهُمْ فَلَا تَخْشَوْهُمْ وَاخْشَوْنِي وَلِأُتِمَّ نِعْمَتِي عَلَيْكُمْ وَلَعَلَّكُمْ تَهْتَدُونَ ١٥٠

حُجَّةٌ ḥujjatun · any argument

And from wherever you go out [for prayer], turn your face toward al-Masjid al-Ḥarām. And wherever you [believers] may be, turn your faces toward it in order that the people will not have any argument against you, except for those of them who commit wrong; so fear them not but fear Me. And [it is] so I may complete My favor upon you and that you may be guided, (Surah Al-Baqarah, 2:150)

إِنَّ الصَّفَا وَالْمَرْوَةَ مِن شَعَائِرِ اللَّهِ فَمَنْ حَجَّ الْبَيْتَ أَوِ اعْتَمَرَ فَلَا جُنَاحَ عَلَيْهِ أَن يَطَّوَّفَ بِهِمَا وَمَن تَطَوَّعَ خَيْرًا فَإِنَّ اللَّهَ شَاكِرٌ عَلِيمٌ ١٥٨

حَجَّ ḥajja · performs Hajj

Indeed, aṣ-Ṣafā and al-Marwah are among the symbols of Allāh. So whoever makes ḥajj [pilgrimage] to the House or performs ʿumrah - there is no blame upon him for walking between them. And whoever volunteers good - then indeed, Allāh is Appreciative and Knowing. (Surah Al-Baqarah, 2:158)

فِيهِ آيَاتٌ بَيِّنَاتٌ مَّقَامُ إِبْرَاهِيمَ وَمَن دَخَلَهُ كَانَ آمِنًا وَلِلَّهِ عَلَى النَّاسِ حِجُّ الْبَيْتِ مَنِ اسْتَطَاعَ إِلَيْهِ سَبِيلًا وَمَن كَفَرَ فَإِنَّ اللَّهَ غَنِيٌّ عَنِ الْعَالَمِينَ ٩٧

حِجُّ ḥijju · (is) pilgrimage

In it are clear signs [such as] the standing place of Abraham. And whoever enters it [i.e., the Ḥaram] shall be safe. And [due] to Allāh from the people is a pilgrimage to the House - for whoever is able to find thereto a way. But whoever disbelieves [i.e., refuses] - then indeed, Allāh is free from need of the worlds. (Surah Ali 'Imran, 3:97)
