Musannaf Ibn Abi Shayba 9:768

Muhammad ibn Fudayl narrated to us, from Husayn, from Murrah: "*{So come to your tilth when or how you will}*." He said: The Jews used to mock the Muslims regarding their approach to women. So Allah, Blessed and Exalted is He, revealed: *{Your women are a tilth for you, so come to your tilth when or how you will}*, meaning in the private parts, however you wish.
