Surah Al-Ahzāb (الأحزاب) – Verse 33

وَقَرْنَ فِي بُيُوتِكُنَّ وَلَا تَبَرَّجْنَ تَبَرُّجَ الْجَاهِلِيَّةِ الْأُولَىٰ ۖ وَأَقِمْنَ الصَّلَاةَ وَآتِينَ الزَّكَاةَ وَأَطِعْنَ اللَّهَ وَرَسُولَهُ ۚ إِنَّمَا يُرِيدُ اللَّهُ لِيُذْهِبَ عَنكُمُ الرِّجْسَ أَهْلَ الْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيرًا

Transliteration:

Wa qarna fi buyutikunna wa la tabarrajna tabarruja al-jahiliyyati al-ula wa aqimna as-salata wa atiyna az-zakata wa ati'na Allaha wa rasulahu innama yuridu Allahu li-yudhiba 'ankumu ar-rijsa ahla al-bayti wa yutahhirakum tathiran

Translation:

Stay in your houses, and do not flaunt your finery like the former [days of] ignorance. Maintain the prayer and give the zakāt, and obey Allah and His Apostle. Indeed Allah desires to repel all impurity from you, O People of the Household, and purify you with a thorough purification.
