Narrated Aisha, Ummul Mu'minin:
Asma, daughter of AbuBakr, entered upon the Messenger of Allah () wearing thin clothes. The Messenger of Allah () turned his attention from her. He said: O Asma', when a woman reaches the age of menstruation, it does not suit her that she displays her parts of body except this and this, and he pointed to her face and hands.
Abu Dawud said: This is a mursal tradition (i.e. the narrator who transmitted it from 'Aishah is missing) Khalid b. Duraik did not see 'Aishah.
