Sahih Muslim | Book 8 | Hadith Number 3305

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