Sayyiduna Ibn Umar (may Allah be pleased with them both) married the daughter of his maternal uncle Uthman bin Maz'un. Her mother went to the Prophet (peace and blessings be upon him) and said: My daughter dislikes this. So the Prophet (peace and blessings be upon him) had them separated and said: "Do not marry off orphan girls until you consult them. If they remain silent, that is their consent." Then, after Abdullah, al-Mughirah bin Shu'bah married her.
