وَقَرْنَ فِى بُيُوتِكُنَّ وَلَا تَبَرَّجْنَ تَبَرُّجَ ٱلْجَـٰهِلِيَّةِ ٱلْأُولَىٰ ۖ وَأَقِمْنَ ٱلصَّلَوٰةَ وَءَاتِينَ ٱلزَّكَوٰةَ وَأَطِعْنَ ٱللَّهَ وَرَسُولَهُۥٓ ۚ إِنَّمَا يُرِيدُ ٱللَّهُ لِيُذْهِبَ عَنكُمُ ٱلرِّجْسَ أَهْلَ ٱلْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيرًا

stay at home, and do not flaunt your finery as they used to in the pagan past; keep up the prayer, give the prescribed alms, and obey God and His Messenger. God wishes to keep uncleanness away from you, people of the [Prophet’s] House, and to purify you thoroughly.

وَٱذْكُرْنَ مَا يُتْلَىٰ فِى بُيُوتِكُنَّ مِنْ ءَايَـٰتِ ٱللَّهِ وَٱلْحِكْمَةِ ۚ إِنَّ ٱللَّهَ كَانَ لَطِيفًا خَبِيرًا

Remember what is recited in your houses of God’s revelations and wisdom, for God is all subtle, all aware.
