Section : Asking Consent of Virgins and Women Previously Married for their Persons.

Malik related to me from Abdullah ibn al-Fadl from Nafi ibn Jubayr ibn Mutim from Abdullah ibn Abbas that the Messenger of Allah, may Allah bless him and grant him peace, said, "A woman who has been previously married is more entitled to her person than her guardian, and a virgin must be asked for her consent for herself, and her consent is her silence."
