If a woman from the women of Jannah were to appear ..

Upon the authority of Anas Ibn Maalik (RadhiAllaahu ‘anhu) who said that the Messenger of Allaah  (sallAllaahu 'alayhi wa sallam) said: 

“..If a woman from the women of Jannah were to appear in this world, that which is between (the heavens and the earth) would be filled with her (beautiful) fragrance.. and they would illuminate that which is between the heavens and the earth.. the scarf that is on her head is better than the world and that which is upon it!”
