Quran 33 : 59

بسم الله الرحمن الرحيم

يَا أَيُّهَا النَّبِيُّ قُل لِّأَزْوَاجِكَ وَبَنَاتِكَ وَنِسَاءِ الْمُؤْمِنِينَ يُدْنِينَ عَلَيْهِنَّ مِن جَلَابِيبِهِنَّۚ ذَٰلِكَ أَدْنَىٰ أَن يُعْرَفْنَ فَلَا يُؤْذَيْنَۗ وَكَانَ اللَّهُ غَفُورًا رَّحِيمًا

Aey Nabi! ﷺ khedo apni Biwiyo aur Shabzadiyo aur musalmano ki Aurato ko ke apne upar apni Chadare latkaliya kare yeh zyada karib hay ke Pahechan li jae to Satai na jae. Aur Allah Taalaa Bakhsney wala Meharban hay.
O Prophet! ﷺ Tell thy wives and daughters, and the believing women, that they should cast their outer garments over their persons (when abroad): that is most convenient, that they should be known (as such) and not molested. And Allah is Oft-Forgiving, Most Merciful.
