Musnad Abu Ya'la al-Mawsili 150:299

Musa narrated to us, Yahya narrated to us, from Ibn Jurayj, who said: I heard Ibn Abi Mulaykah narrating from Dhakwan, Abu ‘Amr, from ‘Aishah, from the Prophet (peace be upon him), who said: "Seek the permission of women regarding their private parts (marriage), for the virgin is shy, so she remains silent, and that is her permission."
