Sahih al-Bukhari Book 65, Hadith 281
`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."
May Allah bestow His Mercy on the early emigrant women. When Allah revealed: "... and to draw their veils all over their Juyubihinna (i.e., their bodies, faces, necks and bosoms)..." (V.24:31) they tore their Murat (woolen dresses or waist-binding clothes or aprons etc.) and covered their heads and faces with those torn Muruts.
A man said, "O Allah's Prophet! Will Allah gather the non-believers on their faces on the Day of Resurrection?" He said, "Will not the One Who made him walk on his feet in this world, be able to make him walk on his face on the Day of Resurrection?" (Qatada, a subnarrator, said: Yes, By the Power of Our Lord!)
