Quran Al-Ahzab 33:59
يَٰٓأَيُّهَا ٱلنَّبِيُّ قُل لِّأَزۡوَٰجِكَ وَبَنَاتِكَ وَنِسَآءِ ٱلۡمُؤۡمِنِينَ يُدۡنِينَ عَلَيۡهِنَّ مِن جَلَٰبِيبِهِنَّۚ ذَٰلِكَ أَدۡنَىٰٓ أَن يُعۡرَفۡنَ فَلَا يُؤۡذَيۡنَۗ وَكَانَ ٱللَّهُ غَفُورٗا رَّحِيمٗا ٥٩
Translation
O Prophet, tell your wives and your daughters and the women of the believers to bring down over themselves [part] of their outer garments. That is more suitable that they will be known and not be abused. And ever is Allāh Forgiving and Merciful.
