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-Māʾidah 5:6

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا قُمْتُمْ إِلَى ٱلصَّلَوٰةِ فَٱغْسِلُوا۟ وُجُوهَكُمْ وَأَيْدِيَكُمْ إِلَى ٱلْمَرَافِقِ وَٱمْسَحُوا۟ بِرُءُوسِكُمْ وَأَرْجُلَكُمْ إِلَى ٱلْكَعْبَيْنِ وَإِن كُنتُمْ جُنُبًا فَٱطَّهَّرُوا۟ وَإِن كُنتُم مَّرْضَىٰٓ أَوْ عَلَىٰ سَفَرٍ أَوْ جَآءَ أَحَدٌ مِّنكُم مِّنَ ٱلْغَآئِطِ أَوْ لَٰمَسْتُمُ ٱلنِّسَآءَ فَلَمْ تَجِدُوا۟ مَآءً فَتَيَمَّمُوا۟ صَعِيدًا طَيِّبًا فَٱمْسَحُوا۟ بِوُجُوهِكُمْ وَأَيْدِيكُم مِّنْهُ مَا يُرِيدُ ٱللَّـهُ لِيَجْعَلَ عَلَيْكُم مِّنْ حَرَجٍ وَلَٰكِن يُرِيدُ لِيُطَهِّرَكُمْ وَلِيُتِمَّ نِعْمَتَهُۥ عَلَيْكُمْ لَعَلَّكُمْ تَشْكُرُونَ

O ye who believe! when ye prepare for prayer, wash your faces, and your hands (and arms) to the elbows; Rub your heads (with water); and (wash) your feet to the ankles. If ye are in a state of ceremonial impurity, bathe your whole body. But if ye are ill, or on a journey, or one of you cometh from offices of nature, or ye have been in contact with women, and ye find no water, then take for yourselves clean sand or earth, and rub therewith your faces and hands, Allah doth not wish to place you in a difficulty, but to make you clean, and to complete his favour to you, that ye may be grateful.

Sura al-Aʿrāf 7:82

وَمَا كَانَ جَوَابَ قَوْمِهِۦٓ إِلَّآ أَن قَالُوٓا۟ أَخْرِجُوهُم مِّن قَرْيَتِكُمْ إِنَّهُمْ أُنَاسٌ يَتَطَهَّرُونَ

wa-mā kāna jawāba qawmihi illā an qālū akhrijūhum min qaryatikum innahum unāsun yataṭahharūna

And his people gave no answer but this: they said, "Drive them out of your city: these are indeed men who want to be clean and pure!"

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

lā taqum fīhi abadan la-masjidun ussisa ʿalā l-taqwā min awwali yawmin aḥaqqu an taqūma fīhi fīhi rijālun yuḥibbūna an yataṭahharū wallāhu yuḥibbu l-muṭṭahhirīna

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 al-Naml 27:56

فَمَا كَانَ جَوَابَ قَوْمِهِۦٓ إِلَّآ أَن قَالُوٓا۟ أَخْرِجُوٓا۟ ءَالَ لُوطٍ مِّن قَرْيَتِكُمْ إِنَّهُمْ أُنَاسٌ يَتَطَهَّرُونَ

fa-mā kāna jawāba qawmihi illā an qālū akhrijū āla lūṭin min qaryatikum innahum unāsun yataṭahharūna

But his people gave no other answer but this: they said, "Drive out the followers of Lut from your city: these are indeed men who want to be clean and pure!"
