I asked Allah's Messenger (ﷺ) about a virgin whose marriage is solemnised by her guardian, whether it was necessary or not to consult her. Allah's Messerger (ﷺ) said: Yes, she must be consulted. 'A'isha reported: I told him that she feels shy, whereupon Allah's Messenger (ﷺ) said: Her silence implies her consent.
