﴿ وَقَرْنَ فِى بُيُوتِكُنَّ وَلَا تَبَرَّجْنَ تَبَرُّجَ ٱلْجَٰهِلِيَّةِ ٱلْأُولَىٰ ۖ وَأَقِمْنَ ٱلصَّلَوٰةَ وَءَاتِينَ ٱلزَّكَوٰةَ وَأَطِعْنَ ٱللَّهَ وَرَسُولَهُۥٓ ۚ إِنَّمَا يُرِيدُ ٱللَّهُ لِيُذْهِبَ عَنكُمُ ٱلرِّجْسَ أَهْلَ ٱلْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيرًۭا ﴾

“And abide quietly in your homes, and do not flaunt your charms as they used to flaunt them in the old days of pagan ignorance; and be constant in prayer, and render the purifying dues, and pay heed unto God and His Apostle: for God only wants to remove from you all that might be loathsome, O you members of the [Prophet’s] household, and to purify you to utmost purity.”
