It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he married the daughter of his maternal uncle, Uthman bin Maz'un. He said: Her mother came to the Prophet (peace and blessings be upon him) and said: My daughter dislikes (this marriage), by Allah! So the Messenger of Allah (peace and blessings be upon him) ordered him to separate from her, and he separated from her. And he (peace and blessings be upon him) said: "Do not marry off women until you have consulted them; if they remain silent, that is their permission." Later, after Abdullah, Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) married her. This is a great and sahih (authentic) hadith on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
