Sura al-Baqara 2:125

وَإِذْ جَعَلْنَا ٱلْبَيْتَ مَثَابَةً لِّلنَّاسِ وَأَمْنًا وَٱتَّخِذُوا۟ مِن مَّقَامِ إِبْرَٰهِـۧمَ مُصَلًّى وَعَهِدْنَآ إِلَىٰٓ إِبْرَٰهِـۧمَ وَإِسْمَٰعِيلَ أَن طَهِّرَا بَيْتِىَ لِلطَّآئِفِينَ وَٱلْعَٰكِفِينَ وَٱلرُّكَّعِ ٱلسُّجُودِ

Remember We made the House a place of assembly for men and a place of safety; and take ye the station of Abraham as a place of prayer; and We covenanted with Abraham and Isma'il, that they should sanctify My House for those who compass it round, or use it as a retreat, or bow, or prostrate themselves (therein in prayer).

Sura Āl-ʿImrān 3:42

وَإِذْ قَالَتِ ٱلْمَلَٰٓئِكَةُ يَٰمَرْيَمُ إِنَّ ٱللَّـهَ ٱصْطَفَىٰكِ وَطَهَّرَكِ وَٱصْطَفَىٰكِ عَلَىٰ نِسَآءِ ٱلْعَٰلَمِينَ

wa-idh qālati l-malāʾikatu yā-maryamu inna allāha iṣṭafāki wa-ṭahharaki wa-iṣṭafāki ʿalā nisāʾi l-ʿālamīna

Behold! the angels said: "O Mary! Allah hath chosen thee and purified thee- chosen thee above the women of all nations.

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-Māʾidah 5:41

يَٰٓأَيُّهَا ٱلرَّسُولُ لَا يَحْزُنكَ ٱلَّذِينَ يُسَٰرِعُونَ فِى ٱلْكُفْرِ مِنَ ٱلَّذِينَ قَالُوٓا۟ ءَامَنَّا بِأَفْوَٰهِهِمْ وَلَمْ تُؤْمِن قُلُوبُهُمْ وَمِنَ ٱلَّذِينَ هَادُوا۟ سَمَّٰعُونَ لِلْكَذِبِ سَمَّٰعُونَ لِقَوْمٍ ءَاخَرِينَ لَمْ يَأْتُوكَ يُحَرِّفُونَ ٱلْكَلِمَ مِنۢ بَعْدِ مَوَاضِعِهِۦ يَقُولُونَ إِنْ أُوتِيتُمْ هَٰذَا فَخُذُوهُ وَإِن لَّمْ تُؤْتَوْهُ فَٱحْذَرُوا۟ وَمَن يُرِدِ ٱللَّـهُ فِتْنَتَهُۥ فَلَن تَمْلِكَ لَهُۥ مِنَ ٱللَّـهِ شَيْـًٔا أُو۟لَٰٓئِكَ ٱلَّذِينَ لَمْ يُرِدِ ٱللَّـهُ أَن يُطَهِّرَ قُلُوبَهُمْ لَهُمْ فِى ٱلدُّنْيَا خِزْىٌ وَلَهُمْ فِى ٱلْأَخِرَةِ عَذَابٌ عَظِيمٌ

O Messenger! let not those grieve thee, who race each other into unbelief: (whether it be) among those who say "We believe" with their lips but whose hearts have no faith; or it be among the Jews,- men who will listen to any lie,- will listen even to others who have never so much as come to thee. They change the words from their (right) times and places: they say, "If ye are given this, take it, but if not, beware!" If any one's trial is intended by Allah, thou hast no authority in the least for him against Allah. For such - it is not Allah's will to purify their hearts. For them there is disgrace in this world, and in the Hereafter a heavy punishment.

Sura al-Anfāl 8:11

إِذْ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةً مِّنْهُ وَيُنَزِّلُ عَلَيْكُم مِّنَ ٱلسَّمَآءِ مَآءً لِّيُطَهِّرَكُم بِهِۦ وَيُذْهِبَ عَنكُمْ رِجْزَ ٱلشَّيْطَٰنِ وَلِيَرْبِطَ عَلَىٰ قُلُوبِكُمْ وَيُثَبِّتَ بِهِ ٱلْأَقْدَامَ

Remember He covered you with a sort of drowsiness, to give you calm as from Himself, and he caused rain to descend on you from heaven, to clean you therewith, to remove from you the stain of Satan, to strengthen your hearts, and to plant your feet firmly therewith.

Sura al-Tawbah 9:103

خُذْ مِنْ أَمْوَٰلِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكِّيهِم بِهَا وَصَلِّ عَلَيْهِمْ إِنَّ صَلَوٰتَكَ سَكَنٌ لَّهُمْ وَٱللَّـهُ سَمِيعٌ عَلِيمٌ

khudh min amwālihim ṣadaqatan tuṭahhiruhum wa-tuzakkīhim bihā wa-ṣalli ʿalayhim inna ṣalātaka sakanun lahum wallāhu samīʿun ʿalīmun

Of their goods, take alms, that so thou mightest purify and sanctify them; and pray on their behalf. Verily thy prayers are a source of security for them: And Allah is One Who heareth and knoweth.

Sura al-Ḥajj 22:26

وَإِذْ بَوَّأْنَا لِإِبْرَٰهِيمَ مَكَانَ ٱلْبَيْتِ أَن لَّا تُشْرِكْ بِى شَيْـًٔا وَطَهِّرْ بَيْتِىَ لِلطَّآئِفِينَ وَٱلْقَآئِمِينَ وَٱلرُّكَّعِ ٱلسُّجُودِ

Behold! We gave the site, to Abraham, of the (Sacred) House, (saying): "Associate not anything (in worship) with Me; and sanctify My House for those who compass it round, or stand up, or bow, or prostrate themselves (therein in prayer).

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-Muddaththir 74:4

وَثِيَابَكَ فَطَهِّرْ

wa-thiyābaka fa-ṭahhir

And thy garments keep free from stain!
