It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "A previously married woman (thayyib) has more right over herself than her guardian, and a virgin's permission should be sought, and her silence is her acknowledgement."
