Read and reflect on verse 3592 from Surah Al-Ahzaab: O Prophet! Tell thy wives and thy daughters, as well as all [other] believing women, that they should draw over themselves some of their outer garment...
يَا أَيُّهَا النَّبِيُّ قُلْ لِأَزْوَاجِكَ وَبَنَاتِكَ وَنِسَاءِ الْمُؤْمِنِينَ يُدْنِينَ عَلَيْهِنَّ مِنْ جَلَابِيبِهِنَّ ۚ ذَٰلِكَ أَدْنَىٰ أَنْ يُعْرَفْنَ فَلَا يُؤْذَيْنَ ۗ وَكَانَ اللَّهُ غَفُورًا رَحِيمًا
O Prophet! Tell thy wives and thy daughters, as well as all [other] believing women, that they should draw over themselves some of their outer garments [when in public]: this will be more conducive to their being recognized [as decent women] and not annoyed. But [withal,] God is indeed much- forgiving, a dispenser of grace!
