Allah az’zawajal says to the holy Prophet Sallalahu alaihi wassalam in the Holy Quran translation from kanzul imaan;
O Prophet! Say to your wives and your daughters and the women of the faithful to draw their outer garments (jilbabs) close around them; that is better that they will be recognized and not annoyed. And Allah is ever Forgiving, Gentle.
[Sura Al Ahzab, Verse 59]
