Sahih al-Bukhari 4759
Narrated Safiya bint Shaiba:
`Aisha used to say: "When (the Verse): "They should draw their veils over their necks and bosoms," 
was revealed, (the ladies) cut their waist sheets at the edges and covered their heads and faces with those cut pieces of cloth."
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ نَافِعٍ، عَنِ الْحَسَنِ بْنِ مُسْلِمٍ، عَنْ صَفِيَّةَ بِنْتِ شَيْبَةَ، أَنَّ عَائِشَةَ ـ رضى الله عنها ـ كَانَتْ تَقُولُ لَمَّا نَزَلَتْ هَذِهِ الآيَةُ ‏{‏وَلْيَضْرِبْنَ بِخُمُرِهِنَّ عَلَى جُيُوبِهِنَّ‏}‏ أَخَذْنَ أُزْرَهُنَّ فَشَقَّقْنَهَا مِنْ قِبَلِ الْحَوَاشِي فَاخْتَمَرْنَ بِهَا‏.‏
