The root خ ل ص (kh-l-ṣ) in the Quran

قُلْ إِن كَانَتْ لَكُمُ ٱلدَّارُ ٱلْـَٔاخِرَةُ عِندَ ٱللَّهِ خَالِصَةً مِّن دُونِ ٱلنَّاسِ فَتَمَنَّوُا۟ ٱلْمَوْتَ إِن كُنتُمْ صَٰدِقِينَ ۝٩٤

Say, [O Muḥammad], "If the home of the Hereafter with Allāh is for you alone and not the [other] people, then wish for death, if you should be truthful."

قُلْ أَتُحَآجُّونَنَا فِى ٱللَّهِ وَهُوَ رَبُّنَا وَرَبُّكُمْ وَلَنَآ أَعْمَٰلُنَا وَلَكُمْ أَعْمَٰلُكُمْ وَنَحْنُ لَهُۥ مُخْلِصُونَ ۝١٣٩

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."

إِلَّا ٱلَّذِينَ تَابُوا۟ وَأَصْلَحُوا۟ وَٱعْتَصَمُوا۟ بِٱللَّهِ وَأَخْلَصُوا۟ دِينَهُمْ لِلَّهِ فَأُو۟لَٰٓئِكَ مَعَ ٱلْمُؤْمِنِينَ وَسَوْفَ يُؤْتِ ٱللَّهُ ٱلْمُؤْمِنِينَ أَجْرًا عَظِيمًا ۝١٤٦

Except for those who repent, correct themselves, hold fast to Allāh, and are sincere in their religion for Allāh, for those will be with the believers. And Allāh is going to give the believers a great reward.

وَقَالُوا۟ مَا فِى بُطُونِ هَٰذِهِ ٱلْأَنْعَٰمِ خَالِصَةٌ لِّذُكُورِنَا وَمُحَرَّمٌ عَلَىٰٓ أَزْوَٰجِنَا وَإِن يَكُن مَّيْتَةً فَهُمْ فِيهِ شُرَكَآءُ سَيَجْزِيهِمْ وَصْفَهُمْ إِنَّهُۥ حَكِيمٌ عَلِيمٌ ۝١٣٩

And they say, "What is in the bellies of these animals is exclusively for our males and forbidden to our females. But if it is [born] dead, then all of them have shares therein." He will punish them for their description. Indeed, He is Wise and Knowing.

قُلْ أَمَرَ رَبِّى بِٱلْقِسْطِ وَأَقِيمُوا۟ وُجُوهَكُمْ عِندَ كُلِّ مَسْجِدٍ وَٱدْعُوهُ مُخْلِصِينَ لَهُ ٱلدِّينَ كَمَا بَدَأَكُمْ تَعُودُونَ ۝٢٩

Say, [O Muḥammad], "My Lord has ordered justice and that you direct yourselves [to the Qiblah] at every place [or time] of prostration, and invoke Him, sincere to Him in religion." Just as He originated you, you will return [to life] -

قُلْ مَنْ حَرَّمَ زِينَةَ ٱللَّهِ ٱلَّتِىٓ أَخْرَجَ لِعِبَادِهِۦ وَٱلطَّيِّبَٰتِ مِنَ ٱلرِّزْقِ قُلْ هِىَ لِلَّذِينَ ءَامَنُوا۟ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا خَالِصَةً يَوْمَ ٱلْقِيَٰمَةِ كَذَٰلِكَ نُفَصِّلُ ٱلْـَٔايَٰتِ لِقَوْمٍ يَعْلَمُونَ ۝٣٢

Say, "Who has forbidden the adornment of [i.e., from] Allāh which He has produced for His servants and the good [lawful] things of provision?" Say, "They are for those who believed during the life of this world, exclusively [for them] on the Day of Resurrection." Thus do We detail the verses for a people who know.

هُوَ ٱلَّذِى يُسَيِّرُكُمْ فِى ٱلْبَرِّ وَٱلْبَحْرِ حَتَّىٰٓ إِذَا كُنتُمْ فِى ٱلْفُلْكِ وَجَرَيْنَ بِهِم بِرِيحٍ طَيِّبَةٍ وَفَرِحُوا۟ بِهَا جَآءَتْهَا رِيحٌ عَاصِفٌ وَجَآءَهُمُ ٱلْمَوْجُ مِن كُلِّ مَكَانٍ وَظَنُّوٓا۟ أَنَّهُمْ أُحِيطَ بِهِمْ دَعَوُا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ لَئِنْ أَنجَيْتَنَا مِنْ هَٰذِهِۦ لَنَكُونَنَّ مِنَ ٱلشَّٰكِرِينَ ۝٢٢

It is He who enables you to travel on land and sea until, when you are in ships and they sail with them by a good wind and they rejoice therein, there comes a storm wind and the waves come upon them from every place and they expect to be engulfed, they supplicate Allāh, sincere to Him in religion, "If You should save us from this, we will surely be among the thankful."

وَلَقَدْ هَمَّتْ بِهِۦ وَهَمَّ بِهَا لَوْلَآ أَن رَّءَا بُرْهَٰنَ رَبِّهِۦ كَذَٰلِكَ لِنَصْرِفَ عَنْهُ ٱلسُّوٓءَ وَٱلْفَحْشَآءَ إِنَّهُۥ مِنْ عِبَادِنَا ٱلْمُخْلَصِينَ ۝٢٤

And she certainly determined [to seduce] him, and he would have inclined to her had he not seen the proof [i.e., sign] of his Lord. And thus [it was] that We should avert from him evil and immorality. Indeed, he was of Our chosen servants.

وَقَالَ ٱلْمَلِكُ ٱئْتُونِى بِهِۦٓ أَسْتَخْلِصْهُ لِنَفْسِى فَلَمَّا كَلَّمَهُۥ قَالَ إِنَّكَ ٱلْيَوْمَ لَدَيْنَا مَكِينٌ أَمِينٌ ۝٥٤

And the king said, "Bring him to me; I will appoint him exclusively for myself." And when he spoke to him, he said, "Indeed, you are today established [in position] and trusted."

فَلَمَّا ٱسْتَيْـَٔسُوا۟ مِنْهُ خَلَصُوا۟ نَجِيًّا قَالَ كَبِيرُهُمْ أَلَمْ تَعْلَمُوٓا۟ أَنَّ أَبَاكُمْ قَدْ أَخَذَ عَلَيْكُم مَّوْثِقًا مِّنَ ٱللَّهِ وَمِن قَبْلُ مَا فَرَّطتُمْ فِى يُوسُفَ فَلَنْ أَبْرَحَ ٱلْأَرْضَ حَتَّىٰ يَأْذَنَ لِىٓ أَبِىٓ أَوْ يَحْكُمَ ٱللَّهُ لِى وَهُوَ خَيْرُ ٱلْحَٰكِمِينَ ۝٨٠

So when they had despaired of him, they secluded themselves in private consultation. The eldest of them said, "Do you not know that your father has taken upon you an oath by Allāh and [that] before you failed in [your duty to] Joseph? So I will never leave [this] land until my father permits me or Allāh decides for me, and He is the best of judges.

إِلَّا عِبَادَكَ مِنْهُمُ ٱلْمُخْلَصِينَ ۝٤٠

Except, among them, Your chosen servants."

وَإِنَّ لَكُمْ فِى ٱلْأَنْعَٰمِ لَعِبْرَةً نُّسْقِيكُم مِّمَّا فِى بُطُونِهِۦ مِنۢ بَيْنِ فَرْثٍ وَدَمٍ لَّبَنًا خَالِصًا سَآئِغًا لِّلشَّٰرِبِينَ ۝٦٦

And indeed, for you in grazing livestock is a lesson. We give you drink from what is in their bellies - between excretion and blood - pure milk, palatable to drinkers.

وَٱذْكُرْ فِى ٱلْكِتَٰبِ مُوسَىٰٓ إِنَّهُۥ كَانَ مُخْلَصًا وَكَانَ رَسُولًا نَّبِيًّا ۝٥١

And mention in the Book, Moses. Indeed, he was chosen, and he was a messenger and a prophet.

فَإِذَا رَكِبُوا۟ فِى ٱلْفُلْكِ دَعَوُا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ فَلَمَّا نَجَّىٰهُمْ إِلَى ٱلْبَرِّ إِذَا هُمْ يُشْرِكُونَ ۝٦٥

And when they board a ship, they supplicate Allāh, sincere to Him in religion [i.e., faith and hope]. But when He delivers them to the land, at once they associate others with Him

وَإِذَا غَشِيَهُم مَّوْجٌ كَٱلظُّلَلِ دَعَوُا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ فَلَمَّا نَجَّىٰهُمْ إِلَى ٱلْبَرِّ فَمِنْهُم مُّقْتَصِدٌ وَمَا يَجْحَدُ بِـَٔايَٰتِنَآ إِلَّا كُلُّ خَتَّارٍ كَفُورٍ ۝٣٢

And when waves come over them like canopies, they supplicate Allāh, sincere to Him in religion [i.e., faith]. But when He delivers them to the land, there are [some] of them who are moderate [in faith]. And none rejects Our signs except everyone treacherous and ungrateful.

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.

إِلَّا عِبَادَ ٱللَّهِ ٱلْمُخْلَصِينَ ۝٤٠

But not the chosen servants of Allāh.

إِلَّا عِبَادَ ٱللَّهِ ٱلْمُخْلَصِينَ ۝٧٤

But not the chosen servants of Allāh.

إِلَّا عِبَادَ ٱللَّهِ ٱلْمُخْلَصِينَ ۝١٢٨

Except the chosen servants of Allāh.

إِلَّا عِبَادَ ٱللَّهِ ٱلْمُخْلَصِينَ ۝١٦٠

Except the chosen servants of Allāh [who do not share in that sin].

لَكُنَّا عِبَادَ ٱللَّهِ ٱلْمُخْلَصِينَ ۝١٦٩

We would have been the chosen servants of Allāh."

إِنَّآ أَخْلَصْنَٰهُم بِخَالِصَةٍ ذِكْرَى ٱلدَّارِ ۝٤٦

Indeed, We chose them for an exclusive quality: remembrance of the home [of the Hereafter].

إِلَّا عِبَادَكَ مِنْهُمُ ٱلْمُخْلَصِينَ ۝٨٣

Except, among them, Your chosen servants."

إِنَّآ أَنزَلْنَآ إِلَيْكَ ٱلْكِتَٰبَ بِٱلْحَقِّ فَٱعْبُدِ ٱللَّهَ مُخْلِصًا لَّهُ ٱلدِّينَ ۝٢

Indeed, We have sent down to you the Book, [O Muḥammad], in truth. So worship Allāh, [being] sincere to Him in religion.

أَلَا لِلَّهِ ٱلدِّينُ ٱلْخَالِصُ وَٱلَّذِينَ ٱتَّخَذُوا۟ مِن دُونِهِۦٓ أَوْلِيَآءَ مَا نَعْبُدُهُمْ إِلَّا لِيُقَرِّبُونَآ إِلَى ٱللَّهِ زُلْفَىٰٓ إِنَّ ٱللَّهَ يَحْكُمُ بَيْنَهُمْ فِى مَا هُمْ فِيهِ يَخْتَلِفُونَ إِنَّ ٱللَّهَ لَا يَهْدِى مَنْ هُوَ كَٰذِبٌ كَفَّارٌ ۝٣

Unquestionably, for Allāh is the pure religion. And those who take protectors besides Him [say], "We only worship them that they may bring us nearer to Allāh in position." Indeed, Allāh will judge between them concerning that over which they differ. Indeed, Allāh does not guide he who is a liar and [confirmed] disbeliever.

قُلْ إِنِّىٓ أُمِرْتُ أَنْ أَعْبُدَ ٱللَّهَ مُخْلِصًا لَّهُ ٱلدِّينَ ۝١١

Say, [O Muḥammad], "Indeed, I have been commanded to worship Allāh, [being] sincere to Him in religion.

قُلِ ٱللَّهَ أَعْبُدُ مُخْلِصًا لَّهُۥ دِينِى ۝١٤

Say, "Allāh [alone] do I worship, sincere to Him in my religion,

فَٱدْعُوا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ وَلَوْ كَرِهَ ٱلْكَٰفِرُونَ ۝١٤

So invoke Allāh, [being] sincere to Him in religion, although the disbelievers dislike it.

هُوَ ٱلْحَىُّ لَآ إِلَٰهَ إِلَّا هُوَ فَٱدْعُوهُ مُخْلِصِينَ لَهُ ٱلدِّينَ ٱلْحَمْدُ لِلَّهِ رَبِّ ٱلْعَٰلَمِينَ ۝٦٥

He is the Ever-Living; there is no deity except Him, so call upon Him, [being] sincere to Him in religion. [All] praise is [due] to Allāh, Lord of the worlds.

وَمَآ أُمِرُوٓا۟ إِلَّا لِيَعْبُدُوا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ حُنَفَآءَ وَيُقِيمُوا۟ ٱلصَّلَوٰةَ وَيُؤْتُوا۟ ٱلزَّكَوٰةَ وَذَٰلِكَ دِينُ ٱلْقَيِّمَةِ ۝٥

And they were not commanded except to worship Allāh, [being] sincere to Him in religion, inclining to truth, and to establish prayer and to give zakāh. And that is the correct religion.
