Abu Hurairah reported the Prophet(ﷺ) as saying “ A woman who has been previously married should not be married until her permission is asked nor should a virgin be married without her permission. “They (the people) asked “What is her permission, Apostle of Allaah(ﷺ)? He replied “it is by her keeping silence.”
Sunan Abi Dawud Book 12, Hadith 47
