Sura al-Baqara 2:222

وَيَسْـَٔلُونَكَ عَنِ ٱلْمَحِيضِ قُلْ هُوَ أَذًى فَٱعْتَزِلُوا۟ ٱلنِّسَآءَ فِى ٱلْمَحِيضِ وَلَا تَقْرَبُوهُنَّ حَتَّىٰ يَطْهُرْنَ فَإِذَا تَطَهَّرْنَ فَأْتُوهُنَّ مِنْ حَيْثُ أَمَرَكُمُ ٱللَّـهُ إِنَّ ٱللَّـهَ يُحِبُّ ٱلتَّوَّٰبِينَ وَيُحِبُّ ٱلْمُتَطَهِّرِينَ

wa-yasʾalūnaka ʿani l-maḥīḍi qul huwa adhan faʿtazilū l-nisāʾa fī l-maḥīḍi wa-lā taqrabūhunna ḥattā yaṭhurna fa-idhā taṭahharna fatūhunna min ḥaythu amarakumu allāhu inna allāha yuḥibbu l-tawwābīna wa-yuḥibbu l-mutaṭahhirīna

They ask thee concerning women's courses. Say: They are a hurt and a pollution: So keep away from women in their courses, and do not approach them until they are clean. But when they have purified themselves, ye may approach them in any manner, time, or place ordained for you by Allah. For Allah loves those who turn to Him constantly and He loves those who keep themselves pure and clean.

Sura al-Baqara 2:232

وَإِذَا طَلَّقْتُمُ ٱلنِّسَآءَ فَبَلَغْنَ أَجَلَهُنَّ فَلَا تَعْضُلُوهُنَّ أَن يَنكِحْنَ أَزْوَٰجَهُنَّ إِذَا تَرَٰضَوْا۟ بَيْنَهُم بِٱلْمَعْرُوفِ ذَٰلِكَ يُوعَظُ بِهِۦ مَن كَانَ مِنكُمْ يُؤْمِنُ بِٱللَّـهِ وَٱلْيَوْمِ ٱلْأَخِرِ ذَٰلِكُمْ أَزْكَىٰ لَكُمْ وَأَطْهَرُ وَٱللَّـهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ

wa-idhā ṭallaqtumu l-nisāʾa fa-balaghna ajalahunna fa-lā taʿḍulūhunna an yankiḥna azwājahunna idhā tarāḍaw baynahum bil-maʿrūfi dhālika yūʿaẓu bihi man kāna minkum yuʾminū billāhi wa-l-yawmi l-akhiri dhālikum azka la-kum wa-aṭharu wallāhu yaʿlamu wa-antum lā taʿlamūna

When ye divorce women, and they fulfil the term of their ('Iddat), do not prevent them from marrying their (former) husbands, if they mutually agree on equitable terms. This instruction is for all amongst you, who believe in Allah and the Last Day. That is (the course Making for) most virtue and purity amongst you and Allah knows, and ye know not.

Sura Āl-ʿImrān 3:55

إِذْ قَالَ ٱللَّـهُ يَٰعِيسَىٰٓ إِنِّى مُتَوَفِّيكَ وَرَافِعُكَ إِلَىَّ وَمُطَهِّرُكَ مِنَ ٱلَّذِينَ كَفَرُوا۟ وَجَاعِلُ ٱلَّذِينَ ٱتَّبَعُوكَ فَوْقَ ٱلَّذِينَ كَفَرُوٓا۟ إِلَىٰ يَوْمِ ٱلْقِيَٰمَةِ ثُمَّ إِلَىَّ مَرْجِعُكُمْ فَأَحْكُمُ بَيْنَكُمْ فِيمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ

Behold! Allah said: "O Jesus! I will take thee and raise thee to Myself and clear thee (of the falsehoods) of those who blaspheme; I will make those who follow thee superior to those who reject faith, to the Day of Resurrection: Then shall ye all return unto me, and I will judge between you of the matters wherein ye dispute.

Sura al-Tawbah 9:108

لَا تَقُمْ فِيهِ أَبَدًا لَّمَسْجِدٌ أُسِّسَ عَلَى ٱلتَّقْوَىٰ مِنْ أَوَّلِ يَوْمٍ أَحَقُّ أَن تَقُومَ فِيهِ فِيهِ رِجَالٌ يُحِبُّونَ أَن يَتَطَهَّرُوا۟ وَٱللَّـهُ يُحِبُّ ٱلْمُطَّهِّرِينَ

Never stand thou forth therein. There is a mosque whose foundation was laid from the first day on piety; it is more worthy of the standing forth (for prayer) therein. In it are men who love to be purified; and Allah loveth those who make themselves pure.

Sura Hūd 11:78

وَجَآءَهُۥ قَوْمُهُۥ يُهْرَعُونَ إِلَيْهِ وَمِن قَبْلُ كَانُوا۟ يَعْمَلُونَ ٱلسَّيِّـَٔاتِ قَالَ يَٰقَوْمِ هَٰٓؤُلَآءِ بَنَاتِى هُنَّ أَطْهَرُ لَكُمْ فَٱتَّقُوا۟ ٱللَّـهَ وَلَا تُخْزُونِ فِى ضَيْفِىٓ أَلَيْسَ مِنكُمْ رَجُلٌ رَّشِيدٌ

And his people came rushing towards him, and they had been long in the habit of practising abominations. He said: "O my people! Here are my daughters: they are purer for you (if ye marry)! Now fear Allah, and cover me not with shame about my guests! Is there not among you a single right-minded man?"

Sura al-Aḥzāb 33:33

وَقَرْنَ فِى بُيُوتِكُنَّ وَلَا تَبَرَّجْنَ تَبَرُّجَ ٱلْجَٰهِلِيَّةِ ٱلْأُولَىٰ وَأَقِمْنَ ٱلصَّلَوٰةَ وَءَاتِينَ ٱلزَّكَوٰةَ وَأَطِعْنَ ٱللَّـهَ وَرَسُولَهُۥٓ إِنَّمَا يُرِيدُ ٱللَّـهُ لِيُذْهِبَ عَنكُمُ ٱلرِّجْسَ أَهْلَ ٱلْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيرًا

And stay quietly in your houses, and make not a dazzling display, like that of the former Times of Ignorance; and establish regular Prayer, and give regular Charity; and obey Allah and His Messenger. And Allah only wishes to remove all abomination from you, ye members of the Family, and to make you pure and spotless.

Sura al-Aḥzāb 33:53

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَدْخُلُوا۟ بُيُوتَ ٱلنَّبِىِّ إِلَّآ أَن يُؤْذَنَ لَكُمْ إِلَىٰ طَعَامٍ غَيْرَ نَٰظِرِينَ إِنَىٰهُ وَلَٰكِنْ إِذَا دُعِيتُمْ فَٱدْخُلُوا۟ فَإِذَا طَعِمْتُمْ فَٱنتَشِرُوا۟ وَلَا مُسْتَـْٔنِسِينَ لِحَدِيثٍ إِنَّ ذَٰلِكُمْ كَانَ يُؤْذِى ٱلنَّبِىَّ فَيَسْتَحْىِۦ مِنكُمْ وَٱللَّـهُ لَا يَسْتَحْىِۦ مِنَ ٱلْحَقِّ وَإِذَا سَأَلْتُمُوهُنَّ مَتَٰعًا فَسْـَٔلُوهُنَّ مِن وَرَآءِ حِجَابٍ ذَٰلِكُمْ أَطْهَرُ لِقُلُوبِكُمْ وَقُلُوبِهِنَّ وَمَا كَانَ لَكُمْ أَن تُؤْذُوا۟ رَسُولَ ٱللَّـهِ وَلَآ أَن تَنكِحُوٓا۟ أَزْوَٰجَهُۥ مِنۢ بَعْدِهِۦٓ أَبَدًا إِنَّ ذَٰلِكُمْ كَانَ عِندَ ٱللَّـهِ عَظِيمًا

O ye who believe! Enter not the Prophet's houses,- until leave is given you,- for a meal, (and then) not (so early as) to wait for its preparation: but when ye are invited, enter; and when ye have taken your meal, disperse, without seeking familiar talk. Such (behaviour) annoys the Prophet: he is ashamed to dismiss you, but Allah is not ashamed (to tell you) the truth. And when ye ask (his ladies) for anything ye want, ask them from before a screen: that makes for greater purity for your hearts and for theirs. Nor is it right for you that ye should annoy Allah's Messenger, or that ye should marry his widows after him at any time. Truly such a thing is in Allah's sight an enormity.

Sura al-Wāqiʿah 56:79

لَّا يَمَسُّهُۥٓ إِلَّا ٱلْمُطَهَّرُونَ

lā yamassuhu illā l-muṭahharūna

Which none shall touch but those who are clean:

Sura al-Mujādilah 58:12

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا نَٰجَيْتُمُ ٱلرَّسُولَ فَقَدِّمُوا۟ بَيْنَ يَدَىْ نَجْوَىٰكُمْ صَدَقَةً ذَٰلِكَ خَيْرٌ لَّكُمْ وَأَطْهَرُ فَإِن لَّمْ تَجِدُوا۟ فَإِنَّ ٱللَّـهَ غَفُورٌ رَّحِيمٌ

O ye who believe! When ye consult the Messenger in private, spend something in charity before your private consultation. That will be best for you, and most conducive to purity (of conduct). But if ye find not (the wherewithal), Allah is Oft-Forgiving, Most Merciful.
