Sahih Bukhari Volume 6, Book 65, Hadith 4760

وَقَالَ أَحْمَدُ بْنُ شَبِيبٍ حَدَّثَنَا أَبِي، عَنْ يُونُسَ، قَالَ ابْنُ شِهَابٍ عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ يَرْحَمُ اللَّهُ نِسَاءَ الْمُهَاجِرَاتِ الأُوَلَ، لَمَّا أَنْزَلَ اللَّهُ ‏{‏وَلْيَضْرِبْنَ بِخُمُرِهِنَّ عَلَى جُيُوبِهِنَّ‏}‏ شَقَّقْنَ مُرُوطَهُنَّ فَاخْتَمَرْنَ بِهِ‏.‏

Narrated Aishah (RA):May Allah bestow His Mercy on the early imigrant women. When Allah revealed : "... and to draw their veils all over their Juyubihinna(i.e., their bodies, faces, necks and bossoms)..."(V.24:31) they tore their Murut(woolen dresses or waist-binding cloths or aprons etc.) and covered their heads and faces with those torn Muruts.
