The Quran root ش ر ك sh-r-k

وَلَتَجِدَنَّهُمْ أَحْرَصَ النَّاسِ عَلَىٰ حَيَاةٍ وَمِنَ الَّذِينَ أَشْرَكُوا يَوَدُّ أَحَدُهُمْ لَوْ يُعَمَّرُ أَلْفَ سَنَةٍ وَمَا هُوَ بِمُزَحْزِحِهِ مِنَ الْعَذَابِ أَن يُعَمَّرَ وَاللَّهُ بَصِيرٌ بِمَا يَعْمَلُونَ ٩٦

أَشْرَكُوا ashrakū · associate[d] partners (with Allah)

And you will surely find them the most greedy of people for life - [even] more than those who associate others with Allāh. One of them wishes that he could be granted life a thousand years, but it would not remove him in the least from the [coming] punishment that he should be granted life. And Allāh is Seeing of what they do. (Surah Al-Baqarah, 2:96)

قُلْ يَا أَهْلَ الْكِتَابِ تَعَالَوْا إِلَىٰ كَلِمَةٍ سَوَاءٍ بَيْنَنَا وَبَيْنَكُمْ أَلَّا نَعْبُدَ إِلَّا اللَّهَ وَلَا نُشْرِكَ بِهِ شَيْئًا وَلَا يَتَّخِذَ بَعْضُنَا بَعْضًا أَرْبَابًا مِّن دُونِ اللَّهِ فَإِن تَوَلَّوْا فَقُولُوا اشْهَدُوا بِأَنَّا مُسْلِمُونَ ٦٤

نُشْرِكَ nush'rika · we associate partners

Say, "O People of the Scripture, come to a word that is equitable between us and you - that we will not worship except Allāh and not associate anything with Him and not take one another as lords instead of Allāh." But if they turn away, then say, "Bear witness that we are Muslims [submitting to Him]." (Surah Ali 'Imran, 3:64)

مَّا يَوَدُّ الَّذِينَ كَفَرُوا مِنْ أَهْلِ الْكِتَابِ وَلَا الْمُشْرِكِينَ أَن يُنَزَّلَ عَلَيْكُم مِّنْ خَيْرٍ مِّن رَّبِّكُمْ وَاللَّهُ يَخْتَصُّ بِرَحْمَتِهِ مَن يَشَاءُ وَاللَّهُ ذُو الْفَضْلِ الْعَظِيمِ ١٠٥

الْمُشْرِكِينَ l-mush'rikīna · those who associate partners (with Allah)

Neither those who disbelieve from the People of the Scripture [i.e., the Jews and Christians] nor the polytheists wish that any good should be sent down to you from your Lord. But Allāh selects for His mercy whom He wills, and Allāh is the possessor of great bounty. (Surah Al-Baqarah, 2:105)

وَلَكُمْ نِصْفُ مَا تَرَكَ أَزْوَاجُكُمْ إِن لَّمْ يَكُن لَّهُنَّ وَلَدٌ فَإِن كَانَ لَهُنَّ وَلَدٌ فَلَكُمُ الرُّبُعُ مِمَّا تَرَكْنَ مِن بَعْدِ وَصِيَّةٍ يُوصِينَ بِهَا أَوْ دَيْنٍ وَلَهُنَّ الرُّبُعُ مِمَّا تَرَكْتُمْ إِن لَّمْ يَكُن لَّكُمْ وَلَدٌ فَإِن كَانَ لَكُمْ وَلَدٌ فَلَهُنَّ الثُّمُنُ مِمَّا تَرَكْتُم مِّن بَعْدِ وَصِيَّةٍ تُوصُونَ بِهَا أَوْ دَيْنٍ وَإِن كَانَ رَجُلٌ يُورَثُ كَلَالَةً أَوِ امْرَأَةٌ وَلَهُ أَخٌ أَوْ أُخْتٌ فَلِكُلِّ وَاحِدٍ مِّنْهُمَا السُّدُسُ فَإِن كَانُوا أَكْثَرَ مِن ذَٰلِكَ فَهُمْ شُرَكَاءُ فِي الثُّلُثِ مِن بَعْدِ وَصِيَّةٍ يُوصَىٰ بِهَا أَوْ دَيْنٍ غَيْرَ مُضَارٍّ وَصِيَّةً مِّنَ اللَّهِ وَاللَّهُ عَلِيمٌ حَلِيمٌ ١٢

شُرَكَاءُ shurakāu · (are) partners

And for you is half of what your wives leave if they have no child. But if they have a child, for you is one fourth of what they leave, after any bequest they [may have] made or debt. And for them [i.e., the wives] is one fourth if you leave no child. But if you leave a child, then for them is an eighth of what you leave, after any bequest you [may have] made or debt. And if a man or woman leaves neither ascendants nor descendants but has a brother or a sister, then for each one of them is a sixth. But if they are more than two, they share a third, after any bequest which was made or debt, as long as there is no detriment [caused]. [This is] an ordinance from Allāh, and Allāh is Knowing and Forbearing. (Surah An-Nisa, 4:12)

وَلَا تَنكِحُوا الْمُشْرِكَاتِ حَتَّىٰ يُؤْمِنَّ وَلَأَمَةٌ مُّؤْمِنَةٌ خَيْرٌ مِّن مُّشْرِكَةٍ وَلَوْ أَعْجَبَتْكُمْ وَلَا تُنكِحُوا الْمُشْرِكِينَ حَتَّىٰ يُؤْمِنُوا وَلَعَبْدٌ مُّؤْمِنٌ خَيْرٌ مِّن مُّشْرِكٍ وَلَوْ أَعْجَبَكُمْ أُولَٰئِكَ يَدْعُونَ إِلَى النَّارِ وَاللَّهُ يَدْعُو إِلَى الْجَنَّةِ وَالْمَغْفِرَةِ بِإِذْنِهِ وَيُبَيِّنُ آيَاتِهِ لِلنَّاسِ لَعَلَّهُمْ يَتَذَكَّرُونَ ٢٢١

الْمُشْرِكَاتِ l-mush'rikāti · [the] polytheistic women

And do not marry polytheistic women until they believe. And a believing slave woman is better than a polytheist, even though she might please you. And do not marry polytheistic men [to your women] until they believe. And a believing slave is better than a polytheist, even though he might please you. Those invite [you] to the Fire, but Allāh invites to Paradise and to forgiveness, by His permission. And He makes clear His verses [i.e., ordinances] to the people that perhaps they may remember. (Surah Al-Baqarah, 2:221)

وَإِذْ قَالَ لُقْمَانُ لِابْنِهِ وَهُوَ يَعِظُهُ يَا بُنَيَّ لَا تُشْرِكْ بِاللَّهِ إِنَّ الشِّرْكَ لَظُلْمٌ عَظِيمٌ ١٣

الشِّرْكَ l-shir'ka · associating partners

And [mention, O Muḥammad], when Luqmān said to his son while he was instructing him, "O my son, do not associate [anything] with Allāh. Indeed, association [with Him] is great injustice." (Surah Luqman, 31:13)
