Quran verses about Purification of the soul (tazkiyah)

رَبَّنَا وَٱبْعَثْ فِيهِمْ رَسُولًا مِّنْهُمْ يَتْلُوا۟ عَلَيْهِمْ ءَايَٰتِكَ وَيُعَلِّمُهُمُ ٱلْكِتَٰبَ وَٱلْحِكْمَةَ وَيُزَكِّيهِمْ إِنَّكَ أَنتَ ٱلْعَزِيزُ ٱلْحَكِيمُ ۝١٢٩

Our Lord, and send among them a messenger from themselves who will recite to them Your verses and teach them the Book and wisdom and purify them. Indeed, You are the Exalted in Might, the Wise."

كَمَآ أَرْسَلْنَا فِيكُمْ رَسُولًا مِّنكُمْ يَتْلُوا۟ عَلَيْكُمْ ءَايَٰتِنَا وَيُزَكِّيكُمْ وَيُعَلِّمُكُمُ ٱلْكِتَٰبَ وَٱلْحِكْمَةَ وَيُعَلِّمُكُم مَّا لَمْ تَكُونُوا۟ تَعْلَمُونَ ۝١٥١

Just as We have sent among you a messenger from yourselves reciting to you Our verses and purifying you and teaching you the Book and wisdom and teaching you that which you did not know.

وَإِذَا طَلَّقْتُمُ ٱلنِّسَآءَ فَبَلَغْنَ أَجَلَهُنَّ فَلَا تَعْضُلُوهُنَّ أَن يَنكِحْنَ أَزْوَٰجَهُنَّ إِذَا تَرَٰضَوْا۟ بَيْنَهُم بِٱلْمَعْرُوفِ ذَٰلِكَ يُوعَظُ بِهِۦ مَن كَانَ مِنكُمْ يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ ذَٰلِكُمْ أَزْكَىٰ لَكُمْ وَأَطْهَرُ وَٱللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ ۝٢٣٢

And when you divorce women and they have fulfilled their term, do not prevent them from remarrying their [former] husbands if they [i.e., all parties] agree among themselves on an acceptable basis. That is instructed to whoever of you believes in Allāh and the Last Day. That is better for you and purer, and Allāh knows and you know not.

لَقَدْ مَنَّ ٱللَّهُ عَلَى ٱلْمُؤْمِنِينَ إِذْ بَعَثَ فِيهِمْ رَسُولًا مِّنْ أَنفُسِهِمْ يَتْلُوا۟ عَلَيْهِمْ ءَايَٰتِهِۦ وَيُزَكِّيهِمْ وَيُعَلِّمُهُمُ ٱلْكِتَٰبَ وَٱلْحِكْمَةَ وَإِن كَانُوا۟ مِن قَبْلُ لَفِى ضَلَٰلٍ مُّبِينٍ ۝١٦٤

Certainly did Allāh confer [great] favor upon the believers when He sent among them a Messenger from themselves, reciting to them His verses and purifying them and teaching them the Book [i.e., the Qur’ān] and wisdom, although they had been before in manifest error.

أَلَمْ تَرَ إِلَى ٱلَّذِينَ يُزَكُّونَ أَنفُسَهُم بَلِ ٱللَّهُ يُزَكِّى مَن يَشَآءُ وَلَا يُظْلَمُونَ فَتِيلًا ۝٤٩

Have you not seen those who claim themselves to be pure? Rather, Allāh purifies whom He wills, and injustice is not done to them, [even] as much as a thread [inside a date seed].

خُذْ مِنْ أَمْوَٰلِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكِّيهِم بِهَا وَصَلِّ عَلَيْهِمْ إِنَّ صَلَوٰتَكَ سَكَنٌ لَّهُمْ وَٱللَّهُ سَمِيعٌ عَلِيمٌ ۝١٠٣

Take, [O Muḥammad], from their wealth a charity by which you purify them and cause them increase, and invoke [Allāh's blessings] upon them. Indeed, your invocations are reassurance for them. And Allāh is Hearing and Knowing.

فَٱنطَلَقَا حَتَّىٰٓ إِذَا لَقِيَا غُلَٰمًا فَقَتَلَهُۥ قَالَ أَقَتَلْتَ نَفْسًا زَكِيَّةًۢ بِغَيْرِ نَفْسٍ لَّقَدْ جِئْتَ شَيْـًٔا نُّكْرًا ۝٧٤

So they set out, until when they met a boy, he [i.e., al-Khiḍr] killed him. [Moses] said, "Have you killed a pure soul for other than [having killed] a soul? You have certainly done a deplorable thing."

قَالَ إِنَّمَآ أَنَا۠ رَسُولُ رَبِّكِ لِأَهَبَ لَكِ غُلَٰمًا زَكِيًّا ۝١٩

He said, "I am only the messenger of your Lord to give you [news of] a pure boy [i.e., son]."

وَمَن يَأْتِهِۦ مُؤْمِنًا قَدْ عَمِلَ ٱلصَّٰلِحَٰتِ فَأُو۟لَٰٓئِكَ لَهُمُ ٱلدَّرَجَٰتُ ٱلْعُلَىٰ ۝٧٥

But whoever comes to Him as a believer having done righteous deeds - for those will be the highest degrees [in position]:

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَتَّبِعُوا۟ خُطُوَٰتِ ٱلشَّيْطَٰنِ وَمَن يَتَّبِعْ خُطُوَٰتِ ٱلشَّيْطَٰنِ فَإِنَّهُۥ يَأْمُرُ بِٱلْفَحْشَآءِ وَٱلْمُنكَرِ وَلَوْلَا فَضْلُ ٱللَّهِ عَلَيْكُمْ وَرَحْمَتُهُۥ مَا زَكَىٰ مِنكُم مِّنْ أَحَدٍ أَبَدًا وَلَٰكِنَّ ٱللَّهَ يُزَكِّى مَن يَشَآءُ وَٱللَّهُ سَمِيعٌ عَلِيمٌ ۝٢١

O you who have believed, do not follow the footsteps of Satan. And whoever follows the footsteps of Satan - indeed, he enjoins immorality and wrongdoing. And if not for the favor of Allāh upon you and His mercy, not one of you would have been pure, ever, but Allāh purifies whom He wills, and Allāh is Hearing and Knowing.

فَإِن لَّمْ تَجِدُوا۟ فِيهَآ أَحَدًا فَلَا تَدْخُلُوهَا حَتَّىٰ يُؤْذَنَ لَكُمْ وَإِن قِيلَ لَكُمُ ٱرْجِعُوا۟ فَٱرْجِعُوا۟ هُوَ أَزْكَىٰ لَكُمْ وَٱللَّهُ بِمَا تَعْمَلُونَ عَلِيمٌ ۝٢٨

And if you do not find anyone therein, do not enter them until permission has been given you. And if it is said to you, "Go back," then go back; it is purer for you. And Allāh is Knowing of what you do.

قُل لِّلْمُؤْمِنِينَ يَغُضُّوا۟ مِنْ أَبْصَٰرِهِمْ وَيَحْفَظُوا۟ فُرُوجَهُمْ ذَٰلِكَ أَزْكَىٰ لَهُمْ إِنَّ ٱللَّهَ خَبِيرٌۢ بِمَا يَصْنَعُونَ ۝٣٠

Tell the believing men to reduce [some] of their vision and guard their private parts. That is purer for them. Indeed, Allāh is [fully] Aware of what they do.

وَلَا تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَىٰ وَإِن تَدْعُ مُثْقَلَةٌ إِلَىٰ حِمْلِهَا لَا يُحْمَلْ مِنْهُ شَىْءٌ وَلَوْ كَانَ ذَا قُرْبَىٰٓ إِنَّمَا تُنذِرُ ٱلَّذِينَ يَخْشَوْنَ رَبَّهُم بِٱلْغَيْبِ وَأَقَامُوا۟ ٱلصَّلَوٰةَ وَمَن تَزَكَّىٰ فَإِنَّمَا يَتَزَكَّىٰ لِنَفْسِهِۦ وَإِلَى ٱللَّهِ ٱلْمَصِيرُ ۝١٨

And no bearer of burdens will bear the burden of another. And if a heavily laden soul calls [another] to [carry some of] its load, nothing of it will be carried, even if he should be a close relative. You can only warn those who fear their Lord unseen and have established prayer. And whoever purifies himself only purifies himself for [the benefit of] his soul. And to Allāh is the [final] destination.
