"...وَلْيَضْرِبْنَ بِخُمُرِهِنَّ عَلَى جُيُوبِهِنَّ..."
...and to draw their veils all over their Juyub.., An-Nur, 31
means that they should wear the outer garment in such a way as to cover their chests and ribs,
so that they will be different from the women of the Jahiliyyah, who did not do that but would pass
in front of men with their chests completely uncovered, and with their necks, forelocks, hair and earrings uncovered...
Khumur (veils) is the plural of Khimar, which means something that covers, and is what is
used to cover the head. This is what is known among the people as a veil...
(their veils all over their Juyub) means, over their necks and chests so that nothing can be seen of them.
